Converting VMware Server VMs to ESX Server 3.02
Our company is drinking the virtualization kool-aid more and more. We have three ESX server licenses in our Bladecenter now, and tonight I migrated the second of four of our Deltek Vision servers (the Reporting tier) from VMware Server hosted on Linux to ESX server (The first was the Deltek Vision SQL Server tier).
First I used my normal rsync backup script and zfs snapshot to create the last backup of the VMware Server version of the report server. Then I just mounted the snapshot via NFS on the ESX server, and used
vmkfstools -i nfsvol/source.vmdk vmfsvol/dest.vmdk
to clone the virtual disk onto one of my SAN vmfs3 datastores. Then I created a new virtual machine in one of the ESX server hosts, pointed it at the imported virtual disk, booted, re-installed vmware tools and rebooted again. It wasn’t too hard and everything works.
The longest part was the vmkfstools import operation, which took about 45 minutes for the 80 GB disk. The SAN was under heavy load at the time doing mail system backups, so I can’t complain.
