VMDK Thick to Thin or Shrink
Posted on 2014-01-14
We are setting up a new backup solution for a client who was previously configured by another source.
ESXI 5.1, Windows Server 2008 R2
Many of the sites have data drives which are 2TB. We will be using Veeam to do the backups, so the snapshots cannot process at this size.
The servers are set up as follows, most all the same:
C: drive is 80gb
D: drive is 2TB and has all data + the Sysvol and NTDS folders
E: drive is 250gb and used for Shadow Copy
The current disks are Thick provisioned. I was going to add a new drive and robocopy the data over, but then saw they had the Sysvol and NTDS folders, so was thinking there may be another way to achieve this.
I've read a few articles about V2V the VM. Can I do this and only pick the Data drive (D:) to convert, then add the new thin provisioned drive and remote the old? What impact will this have since it's holding the sysvol and ntds data?
Are there other options which are safer, easier, etc?
