moving vms from 3.02 to 3.5 - can they be moved back to 3.02 if something goes wrong?

I'm moving a VM from esx 3.02 to a new 3.5 u4 host and a new SAN.

I will be using VMware converter to move the vm, which appears to make a copy of the data files on the new datastore.

If I need to move this VM back to the 3.02 host due to problems, will the 3.5 host have made any changes to the configuration or datafiles that would prevent the rollback from working?

( realise that there will be a copy of the VM on the old san after the export, but if the vm runs for a few days and users have updated data etc. then I can't just fire up the vm on the old san)

Aside from the version of vmtools changing (which shouldn't be a problem either); you shouldn't have a problem at all and if delta's are a problem (going back) you can always convert the 3.5 back to 3.02.

There should be no problem to go back if something goes wrong.

But ESX U4 is a very stable version and if your host and your storage are fully supportes by vmware you should not hAVY ANY PROBLEMS:

Good luck!

Thanks for the advice.

My SAN isn't on the 4.0 HCL, so I'm giving it a miss for a while.
