- You will most likely be prompted to activate the VM after converting it. Remember, that you may need two separate licenses for Windows and the applications to be compliant.
- Not sure what you are asking for with the UUID!?
- Most likely you will need to unjoin/join each time you switch the servers. This depends on the machine account/password policies in your domain.
- VMware Player 6, or even better VMware Workstation 10 which allows to use snapshots, which is very helpful for testing.
What I am concerned about with this approach is data integrity. Can you ensure that no data is accessed/changed while the VM is active? What about dependencies to other systems, when you run the upgrades?
