I just opened a case on this recently... here is tech support response;
Unfortunately, you won't be able to copy an existing repository. You will need to create a new repository and attach a copy of the volumes from the original repository. You will also need to recreate the users and set up the security.
We had a utility that updated the UUID but it didn't work for the newer versions due to changes in the tables so it was pulled from the Knowledge Base. There are currently no plans to provide a utility to update the UUID for the newer versions.
Let me know if you have any questions, otherwise the case will be closed at this time.
