Windchill to 3DEXPERIENCE: verify your migration tool's coverage

“There’s a tool for that.” Before turning that into a schedule, run a real assembly through it: files, parts, relationships, revisions and states. The expected result is a usable structure in the target, with a report that explains any differences.

Native tools have structure and mapping capabilities. PTC documents product and CAD structure exports and attribute transformation rules in its Windchill export/import tools. This does not establish complete Windchill to 3DEXPERIENCE coverage: verify which operations the selected tool supports in the project’s actual versions and configurations.

Verify tool coverage against the objects, relationships and uses you need to migrate.

Pitfall #1: the migrated file is not the migrated data

A CAD model can arrive intact in the target while some of its relationships remain unusable: part references, bills of materials, associated documents, dependencies. Check file integrity, the expected relationships and assembly resolution in the agreed configuration separately. A successful load does not establish all three on its own.

Pitfall #2: assuming the object models map directly

A WTPart, its CAD document and their relationships need target objects and links with validated business meaning. Available types, attributes, revisions and states depend on the configuration of both environments. Some mappings may be direct; others require transformation or a business decision.

For each source type, record the target type, retained attributes, expected relationships, version rules and permitted states. Test this mapping table against real objects. A tool can execute a mapping correctly without that mapping being right for the engineering team.

Pitfall #3: validating the tool only on the simple case

Customisations, specific lifecycle states, parallel revisions and older histories belong in the coverage trial. Depending on the tool and its configuration, these cases may be supported directly, need configuration or require additional processing.

Require a verifiable outcome for each case: data preserved or transformed under an approved rule, explicit differences, then a way to correct and replay. An object type absent from a demonstration remains untested; it is neither automatically covered nor necessarily impossible to migrate.

Pitfall #4: discovering additional sources too late

The scope may fit inside one Windchill instance. It may also include several instances, additional systems or spreadsheets used as a business reference. Inventory them before fixing the data flows.

If several sources describe the same part, decide which is authoritative for each item of data and how to resolve conflicts. Then check whether the selected tool performs that reconciliation or whether it needs to be added to the chain. This is one of the deliverables of a data audit at the start of a project.

Make coverage verifiable

In our five-phase methodology, each object is qualified against the target model, its relationships are checked and its exceptions are diagnosed and replayed. Tool selection follows the required coverage and the trial results.

Acceptance combines structural comparison with verification of CAD usage: see validating a migrated BOM. For scope and object models, continue with the PLM data migration guide.
