Duplicating a virtual machine for testing/development purposes

Last Modified: 2014-10-10
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?

also if there any custom developments or anywhere the urls are hardcoded then you will be in trouble...
Yes, sys prep the machines otherwise you may have a conflict with the existing machines

If there is any way you can migrate your VMs to an isolated test server, that would be best. All you'd need is a license for 2008 R2 since Hyper-V is free. That way you avoid the headaches re-integrating your machines to a production network and give yourself a safe place to do this kind of testing in the future.
