Hi,
We haven't been able to completely clone the environments, but you can attempt this:
1. Clone the VM using your infra team.
2. Change the IP references in you WebSphere (assuming your WebSphere is also running on the same machine)
Changing the hostname of a Maximo WebSphere Application Server – A3J Group3. Change the references to the new ip host as applicable in your property files.
4. Renaming and clone works when your environment doesnt have HTTPS enabled.
Its quite a challenge, but you can give it a try. Long run, have a separate R&D environment to test all these changes.
