Migrating VMs with undo disks, snapshots

I've got to migrate a lot of VMWare 1 and MS Virtual Server 2005 R2 VMs to VMWare Server 2 format using VMware-converter 4.0.1. Some of these have undo disks and snapshots assosciated with them that will also need to be converted. How does Converter handle these? Assuming I need to keep the undo disks and snapshots, what's the best thing to do here?

Hi,

If you want to migrate from host 1 to host 2 using VMware converter then you will loose all snapshots.

VMware converter will just take what is current and move that as a Virtual Machine.

If you need to go from VMware Server 1 to VMware Server 2 on the same host then you can just upgrade the host and your snapshots are most likely preserved. I use most likely here as IIRC the snapshots are not garantueed to work while going from version 1 to version 2. In practice however this seems to work fine.

When you need to take the VMs from one host to another host, I would personally just copy the Virtual Machines themselves, with them completely shutdown (not suspend) and would expect it to work afterwards. You can then upgrade the virtual hardware manually on the VMware Server 2 host if you do not need to run the VMs on a Server1 type of host anymore.

Just to clarify I'm going from VMWare Server 1 to VMWare Server 2 on one host (some of the VMs on here have a snapshot) and MS Virtual Server 2005 R2 (some of the VMs on here have undo disks) to VMWare Server 2 on another. I really need to keep the undo disks, and snapshots can they also be converted?

OK, same host. You should be able to keep the snapshots when upgrading from VMware Server 1 to VMware Server 2. No vmware converter needed, just register the VMs again after upgrading.

I was a bit confused by your remark "undo disk" as that was also an old legacy feature in VMware products. I see what you mean now. But it has been a long time since i've used Microsofts virtualisation products.

So just to make sure, they are not snapshots like in VMware products? But the ability to not save changes to the disk?

You can also enable that feature in VMware Server by setting the disk to non persistent.

If by undo disks you mean go back in time, similar to snapshots, then NO i don't think you can migrate that using VMware converter.

coldcloning should work for the MS-VMs
