Create test system from a backup

SOLVED

We have a virtualized server for Sage 300 and a separate virtualized server for SQl Server 2017.   Does anyone have good documentation on how to take the backup, create a new server and then get Sage 300 up and working.

I know how to restore the virtualized servers and rename them.

The main help I need is

1. Rename the database instance so that it does not cause confusion on the network

2. set up Sage 300 to point to this new instance and not the old one.

I can bring up the virtualized servers under a new name with the network connection turned off so that it doesn't cause any network havoc, but not sure the best way to get everything renamed and working together from the two new servers.

Thanks for any help
