Nine Million Objects Into 3DEXPERIENCE Across Multiple Sites, on a Two-Day Go-Live Window

Three source systems fed this migration, and the data in them was not uniform: SOLIDWORKS, AutoCAD, Inventor and ME10 files sat alongside scanned PDFs and ordinary Office documents. The volume came to 8,996,611 objects, relationships and files. The estate was spread across multiple sites, which meant the migration had to be run in two steps and coordinated between them, and the source data carried the usual legacy problems — missing attributes, duplicate records and characters the target system would not accept.

The structure was extracted from the source first, relationships and dependencies included, so that mapping and transformation had something reliable to work against. Rather than move everything, a selective strategy carried only the latest released data plus the initial non-released data. SteepGraph’s Data Migration Framework automated the runs. The constraint that shaped the whole programme was the go-live window: two to three days, which left no room for a re-run, so the final cutover used a delta migration carrying only what had changed since the previous pass.
