I have a fairly big project coming up in which I need to upgrade a third party application currently running on a hyperv 2008 R2 host. The application and its backend database reside on the same VM. The client portion of this application resides on a separate VM also running on a hyperv 2008 R2 host.
Instead of performing the upgrades on the production systems I want to create duplicate/mirror copies of these two systems. Unfortunately, I do not have a test/development network segment to put these system in and I believe they will require access to resources in order to function properly. Resources such as Active Directory.
My plan is to simply take a copy of the .vhd files, attach them to newly created VMs. Bring the VMs up with no network connection:
- change the name
- change the IP address
- join them back to the domain after renaming & readdressing them and turning network connections back on.
Am I missing a step? Should I sys prep these systems in order to remove the SIDs, etc?
