In my vSphere 5.0 environment, I want to take a snapshot of a Windows 2008 E vm as a temporary backup. Then, on Saturday, I want to boot the running W2008 E vm to a Windows 2008 R2 iso and reinstall the operating system.
Note: I have to bypass the upgrade wizard and do a full installation.
Anyway, I am checking with pros here in case my plan is an ill-fated one. Could I restore the snapshot to Windows 2008 E if I couldn't get the R2's apps to work before the Monday buzzer rings? I have used snapshots in the past as assurance for developers who were making website changes or upgrading Visual Studio, and things like that. But I have never used a snapshot in this manner or in this way. So, I wanted to check before making this leap.
Note 2: Sadly, I am in an environment that does not have backups. Also, I realize what I am describing here is not Best Practice, but it is a long story.
I read the documentation on Snapshots in the pubs.vmware.com documentation, but I didn't see my worry addressed directly.
Thanks in advance,
Rich
