I have a Netware 6.5 VM Server with a virtualized 1.5TB Volume and a virtualized 500Gig Volume.

I would like to disconnect the two volume (vmdk files) from the Netware 6.5 host.
Then run the Migration Tool to Transfer ID to a Pre-Migration OES 11 server.
Once the Transfer ID completes I would connect the Netware 6.5 vmdk files to the OES Server.

How big is the risk in losing the volume meta data with this procedure?

The reason for this method is to avoid the initial migration of roughly 2TB of data to the OES 11 server and new vmdk disk files.

Thanks, DK.
