Backup and Restore from CW 7.1.2 to 7.1.3

We have a Clearwell system on version 7.1.3 that is clean with no cases. We have a system that is on version 7.1.2 that has all our cases on.

I'm looking to restore the cases from the v7.1.2 machine to the v7.1.3 machine.

Looking for documentation/how-to's/knowledge articles, etc. on the backup and restore process for this

If you need more info, please let me know.

Thanks.
