Hi,
as 10.5 has been released recently I would prfefer to migrate to 10.5 instead.
You should put your designer projects (models and tasks and CAF UI) under version control.
Then you can just perform a fresh checkout to the new designer workspace and upgrade the projects.
As Designer is Eclipse-based you can use any version control system for which Eclipse Marketplace provides a plugin for.
Additionally this makes it easier when wworking with several developers on your code base.
You should check for Local Service Development feature as well as this allows to versioning IntegrationServer packages too.
As this will be a side-by-side migration any way you should take a snapshot of your database and perform the migration on this snapshot instead of the real database.
Regards,
Holger
