The move from CATIA V5 to 3DEXPERIENCE promises benefits including platform-based collaboration, integrated lifecycle management, and a foundation for digital continuity. At the same time, it is a multi-stage process that involves strategic planning, thoughtful preparation, and careful tool selection.
This migration guide walks you through the strategies, phases, and tools you need to know to ensure a smooth transition from CATIA V5 to 3DEXPERIENCE, as well as tips on mitigating risks and best practices.
3 Migration Strategies for Moving from CATIA V5 to 3DEXPERIENCE
When migrating from CATIA V5 to the 3DEXPERIENCE platform, companies usually choose between a CAD coexistence strategy (keeping the legacy CAD and using it alongside 3DEXPERIENCE) or a full re-authoring strategy (converting entirely to 3DEXPERIENCE’s native CAD).
Often a hybrid approach is adopted, combining both: legacy designs remain while new projects are created natively on 3DEXPERIENCE.
Strategy 1: CAD Coexistence: pragmatic stepping stone to modernize PLM without the cost of switching CAD tools
In this approach, referred to by Dassault Systèmes as Power’By, CATIA V5 data is imported into 3DEXPERIENCE “as is,” while ongoing design authoring continues in CATIA V5. The 3DEXPERIENCE platform manages the V5 models as external CAD objects in the UPS model.
Pros:
- Minimal disruption and risk: no need to convert or recreate models, design integrity and history remain intact.
- Faster migration: plugging in existing files rather than rebuilding them.
- Full PLM capabilities: BOM management, search, change control, and collaboration without CAD tool change.
Cons:
- Ongoing multi-system complexity: Legacy CATIA V5 must still be maintained for editing models, leading to potentially higher IT overhead.
- Not all 3DEXPERIENCE features apply fully to external CAD: Some advanced design functions or model-based processes may require native 3DEXPERIENCE models.
Strategy 2: Full Re-authoring: Converting design data in one unified environment
Instead of bringing V5 data as external attachments, you convert or recreate the designs as native 3DEXPERIENCE objects. This might involve using conversion utilities or manually rebuilding complex models. It’s generally chosen only if the legacy data set is small or if absolutely needed for regulatory/technical reasons.
Pros:
- Full access to advanced capabilities: designs fully integrated with 3DEXPERIENCE features such as parametric links across disciplines, knowledge ware, etc.
- Simplified maintenance and upgrades: retired legacy systems, avoiding long-term cost.
Cons:
- High upfront cost and effort: converting large, complex assemblies or re-authoring by hand can be extremely time-consuming, expensive, and potentially error-prone.
- Significant business disruption: particularly for organizations with a lot of legacy data. If conversion tools don’t capture 100%, or if manual recreation introduces deviations, there could be a risk of losing detail or design intent.
Strategy 3: Hybrid/Phased Approach: Phase out old CAD at your own pace
Many companies opt for this strategy for two typical scenarios:
- Migrate legacy projects using Power’By for speed and continuity but create all new products directly in 3DEXPERIENCE’s native CAD: Over time, the reliance on CATIA V5 diminishes naturally as new designs are on the platform, while old designs are still accessible and editable via Power’By integration.
- Convert only selective high-value legacy models or critical subsystems to native format for deeper integration and keep the rest in Power’By mode: Organization gains experience on 3DEXPERIENCE with minimal risk, then steadily increases native usage.
3DEXPERIENCE Migration Phases
Regardless of the migration strategies, the core data migration phases are essentially the same: assessment and planning, data cleanup, environment setup, mapping and loading into 3DEXPERIENCE, and validating the results.
Phase 1: Assessment and Planning
This phase is to ensure the migration is well-scoped, resourced, and aligned with business goals.
- Start with a comprehensive audit of your existing CATIA V5 environment
- Inventory all CAD Data: how many files, what types (CATParts, CATProducts, CATDrawings), where they reside (local disks, network drives, PDM/PLM systems)
- Evaluate file dependencies: note links between files, assemblies, parts, design tables, catalogues, associated libraries, and legacy components. These will affect migration workflows.
- Identify any integrations: connected systems like ENOVIA SmarTeam, VPM, ERP, and manufacturing systems.
- Define business objectives to align with the migration plan
Are you migrating to improve collaboration, implement PLM practices, or reduce software silos? Consider if partial migration is acceptable (for instance, only active projects vs. all historical data) based on business needs.
- Define your scope
Moving from CATIA V5 to 3DEXPERIENCE could mean different levels of change and project scope: it might be adopting a whole new CAD and PLM solution if you were previously file-based, or it might primarily be a backend migration of data and processes if you already had a PDM (like Designer Central) in place.
Decide if the scope includes CAD files only or also PLM metadata (part numbers, revisions, lifecycle status, user information) and non-CAD documents (like drawings, PDFs, Office files). Also, decide the migration scope: pilot line, one team, or full rollout, moving everything at once?
Additionally, ensure your hardware and infrastructure meet 3DEXPERIENCE system requirements, and perform a risk assessment to flag potential bottlenecks early.
Phase 2: Data Cleanup
Addressing bad data before any transfer is critical to reducing risk and complexity.
- Revisit the CATIA V5 data inventory from the assessment phase to determine what data is relevant and must be migrated, and what can be archived or left behind.
- Fix data quality problems: Common bad data includes duplicate part numbers or file names, missing or incorrect metadata, broken assembly links, and inconsistent revision schemes, or any legacy behavior that may conflict with 3DEXPERIENCE’s stricter standards.
- Map to the 3DEXPERIENCE data model
Define how metadata will map from the old system to the new one, ensuring part numbers, revision indexes, lifecycle states, and custom attributes align with 3DEXPERIENCE data model conventions.
Plan how to handle scenarios like multiple revisions of the same part, which are supported in 3DEXPERIENCE assemblies (where V5 traditionally allowed only one revision per assembly).
Also, prepare a full backup of the current CATIA V5 data at this stage to safeguard against any data manipulation mistakes.
Phase 3: Environment Setup
This is to ensure the 3DEXPERIENCE environment is ready to receive migrated data and users.
- For on-premises deployment, install the required 3DEXPERIENCE servers, database, application servers, collaboration services, license servers, etc.
- For cloud deployment, coordinate with Dassault Systèmes or your vendor to get your cloud instance configured for your organization, ensuring all necessary roles and licenses are active. Use the DS Cloud Eligibility Checker to see if you are ready to run the 3DEXPERIENCE SaaS platform.
Initial configurations on the 3DEXPERIENCE platform include:
- Create organizational structures and define collaborative spaces, user groups, roles, and permissions.
- If migrating PLM data, configure the data model or any needed custom attributes, naming conventions, or numbering schemes in 3DEXPERIENCE before loading data, so migrated metadata has a proper placeholder. If migrating from PDM, prepare 3DEXPERIENCE’s ENOVIA schema to accept custom fields.
- Plan for adjusting integrations with other enterprise systems (ERP, MES, etc.) to the new platform. For example, update or build connectors or middleware if needed.
After initial configurations, conduct performance tests or dry runs on the new platform with sample data to ensure it can handle anticipated workloads and user counts. Resolve any infrastructure bottlenecks before the migration.
Phase 4: Transfer Data
This is the core technical phase of the project.
- Use authorized migration tools provided by Dassault Systèmes or your implementation partner to move data.
- Execute data transfer and monitor the migration process carefully for errors or warnings. It’s critical to ensure assembly references remain intact after transfer. Any issues (like a missing file or failed object) should be addressed immediately.
Phase 5: Validation
Thoroughly test and verify that migrated data is correct (assemblies, links, metadata) and run performance tests with pilot users.
If PLM processes are involved, run a sample lifecycle change (e.g., release a part or do a design revision in 3DEXPERIENCE) using migrated data to ensure it behaves correctly.
If possible, simulate typical usage scenarios (opening large assemblies, multi-user collaboration, etc.) to validate system performance and stability under load.
Engage a group of power users or key stakeholders to use the 3DEXPERIENCE platform with the migrated data in a pilot run of their daily tasks.
How to Choose the Right Tools for a 3DEXPERIENCE Migration
Dassault Systèmes provides several 3DEXPERIENCE migration tools, each designed for specific purposes.
How these tools help for each migration stage:
Assessment and Planning: Analyze source data, identify issues
- XTA (3DEXPERIENCE Transition Assistant): Validate cloud migration readiness, check for missing references, unsupported file types, and naming issues (no detailed assembly structure analysis).
- EDAT (ENOVIA Deployment Accelerator Toolkit): Perform deep technical assessment for complex or on‑premise migrations, scan entire product structures, identify data quality and dependency issues.
Data Cleanup: Prepare data for a smooth migration
- FBDI (File-Based Design Import): Convert or update individual CATIA V5 files, identify incomplete assemblies.
- EDAT: Provides guided cleanup tasks based on analysis results, resolving naming conflicts and aligning metadata.
Environment Setup: Set up the target system and mapping configuration
- EDAT: For an on-premises environment, ensuring target parameters match source data.
- XTA: For a cloud environment, configure mapping templates and connectivity so the source and 3DEXPERIENCE Cloud speak the same language.
Transfer Data: Execute the migration
- FBDI: For CATIA V5 data managed in files/folders (no integrated PLM), effective for limited or pilot data loads, but less scalable.
- XTA: For cloud migration, import into 3DEXPERIENCE SaaS automatically.
- EDAT: For on-premises migration with existing PDM/PLM like SmarTeam or ENOVIA V5, handle bulk data transfer, and manage complex structures with dependency ordering.
- IMPALA: For large-scale projects with vendor support, given its limited availability and maturity.
Integration with external systems
- XPDM/EIF (Integration frameworks): Connect 3DEXPERIENCE with other PLM/PDM systems (Teamcenter, SmarTeam, etc.) using standard PLM exchange schemas, offer flexibility (can map complex data models) but often slower and requires custom development/configuration.
- API Gateway (3DEXPERIENCE web services): Custom script interface that allows external systems to interact with 3DEXPERIENCE data securely.
Factors to consider when choosing the tools for 3DEXPERIENCE migration
The choice of migration tool depends on your scope, deployment, and data complexity:
- Source system and data complexity: For simple file-based data, FBDI may be sufficient. For complex PLM data, EDAT is better suited.
- Target environment: XTA is the default for 3DEXPERIENCE Cloud; EDAT or XPDM/EIF may be required for on‑
- Volume: EDAT supports batching, delta loads, and restartability for large volumes or deep assemblies, while IMPALA can reduce cutover time for very large migrations.
- Customization needs: Special transformations may require APIs or XPDM/EIF
How to Mitigate Key Risks with 3DEXPERIENCE Migration
Even with planning, hiccups can occur. Here are common pitfalls and how to address them:
Data Quality
Invest in data cleanup up front. Remove redundant or outdated files before migrating. Run analysis tools (Transition Assistant Analyzer, EDAT) to find issues, fix data quality problems, and limit migration scope to what’s needed. This reduces complexity and ensures only high-value data is transferred.
Resistance to Change
Foster a change-friendly culture by communicating the benefits of 3DEXPERIENCE early and often. Gain leadership support and clear executive messaging to improve buy-in and confidence. And of course, comprehensive training and user adoption to help the team adapt to the new platform:
- Role-Based Training: Different users need different levels of proficiency. Tailor training programs for designers, managers, and engineers.
- Hands-On Labs: Encourage experiential learning by providing sandbox environments where users can explore the platform without real-world consequences.
- Ongoing Support: Set up internal champions or super-users who can support their peers during and after the transition.
- Leverage Dassault Resources: Use documentation, e-learning, and community forums to fill knowledge gaps.
Performance Issues
Loading and working with large assemblies or high data volumes in 3DEXPERIENCE may initially show performance issues (e.g., slower load times, network latency on the cloud).
Optimize and test performance: follow best practices for large assembly management (like using lightweight representations, caches, and hardware tuning). Conduct performance tests in a sandbox early to uncover bottlenecks and engage vendor resources for performance tuning if needed.
Integration Complexity
Plan integrations early, identify all connected systems that interface with CATIA, involve their owners in the project, and allocate time for interface development and testing. Consider using API adjustments, middleware, integration frameworks (e.g., XPDM/EIF or REST APIs) for robust data exchange, and if running systems in parallel, implement clear governance so there’s always one authoritative system of record.
Best Practices to Ensure Seamless Transition Without Data Loss
Data integrity is a top priority when moving from CATIA V5 to 3DEXPERIENCE. Consider these migration strategies:
- Phased Migration: Begin with a pilot project or specific team before scaling to the entire organization. This allows for troubleshooting and feedback. Migrate in stages, if possible (by project or department), rather than an all-at-once “big bang.” This reduces risk and makes it easier to manage any issues in smaller batches.
- Automated Tools: Use Dassault’s robust migration tools that preserve design intent such as Transition Assistant for cloud-focused, automated end-to-end migration for supported sources, ENOVIA Deployment Accelerator (EDAT) for on-premises migration managing complex product structures and high volumes, FBDI for testing and fine-tuning loads; XPDM/EIF for connecting or migrating from other PLM systems.
- Link Preservation: Ensure that references within assemblies are maintained post-migration. Broken links can derail productivity and increase manual corrections.
- Validation During Migration: Continuously verify data as it’s loaded. Checking a few representative assemblies or drawings after each batch can catch problems early (e.g., verify that a complex assembly opens correctly and all links are resolved in 3DEXPERIENCE).
- Backup Everything: Before the first file is transferred, create a secure backup of your entire CATIA V5 environment.
