Not sure if this will work, and I would say this is not for the faint of heart, and I’m sure Opto wouldn’t support this, but if you like living on the edge:
Download DB Browser for SQL Lite
Take a backup of your groov (keep a second copy in case this all goes pear shaped)
Extract the backup (I use 7zip - extract the gzip, then untar)
Open the project.grv file in DB Browser
Go to the Browse Data tab
Open Table devices_controllers
Edit the strategyName and strategyFile columns
Click Write Changes
Recompress the project (tar then gzip)
Restore the project to the groov
As long as whatever the pacControlId’s are in the tags_controller table didn’t change when changing the name of your project, then I think this would work. I think this is why they give this warning - since a different project would have different Ids, but in your case, I think they would still be the same.
If you try this, let us know the results!
Edit: Looks like the pacControlId’s are from the ID column of the tag database - these should not have change when making a copy of the project.
