Migrating of Inventor files in Vault




Regarding migrating Inventor files in Vault after a Vault/CAD upgrade. Autodesk’s recommendation is to not migrate files.

Earlier the time to open unmigrated files have been considerable longer than opening migrated files, and because of that there has been a demand to migrate files for customers with large assemblies. However migrating Vaulted Inventor files change them and replaces all referenced files with their latest version. Some customers might not mind that, but other customers would scream out load if that happened!

Autodesk is not open to change the migration tool, and instead pointed out that they have put a lot of effort into making Inventor open old file versions without too much extra time.

Earlier this week we made some tests on opening files in Inventor. We used a customer environment with 2016 files. Inside Inventor 2016 we downloaded a medium size assembly from Vault and opened it in Inventor 2019 (with FULL not EXPRESS mode) both unmigrated and migrated. I found out that in 2019 there wasn’t much difference between them (average times):
  • Unmigrated 2016 files = 1:15 min
  • Migrated to 2019 files = 1:10 min

So:
With latest Inventor the performance doesn’t seem to be the big issue anymore.
Following the Autodesk recommendation to not migrate files would probably be the best idea in order to not mess with the files and risk replaced components.

If a file migration is going to be implemented everyone (both we and the customer) need to be aware of the issue with replaced components and consider if that is an issue or not. At the moment there is no good workaround that will work with a batch migration.
