Environment
3 HP BL460 G1 blades using an EMC NX4 for shared storage in a vSphere ESXi 4.1 cluster
Description
We currently have two file servers running Windows Server 2003 thatwe want to upgrade to Windows server 2008 R2. Both have a thick provisioned secondary virtual disk that is used exclusively for file serving. The first server’s secondary virtual disk is 500GB and the second is 1.4TB. I currently do not have the space on our SAN to bring up two new VM’s with the same storage requirements. What I was thinking of doing is bringing up the two new W2K8R2 VM’s and then disconnecting the secondary drives from the W2K3 VM’s and reconnecting them to the W2K82 VM’s. I assume the process would go like this:
Does this sound like the proper way to go about this type of upgrade? Is there an easier way or a step I’m missing? Thanks in advanced!
The process looks good. I am assuming that these separate VMDK data disks are NOT stored with the current VM correct? It seems like from what you are saying these are just located on separate volumes, if that is the case then yes, this process will work.
The only piece that MAY be helpful to you, I am not sure how many windows shares you have on this data volume (by the sounds of the size probably quite a few) you can just export the lanman shares registry settings from the original host and import this registry key on the new VM. Just make sure you MERGE them, and that the drive locations are the same. Done this many times this way and has worked perfectly. A lot easier then recreating shares/permissions and all that.
Hope thats some help.

Hello...
Well not sure if you have done this yet or not.... I see its a post from back on the Nov 23rd. If you havent I have a few ideas that you should watch out for.

I did a test move by creating a 8GB harddrive with various shares attached to a W2K3 VM and moved it to a W2K8R2 VM. The short hand notes I made are as follows:
I plan to move my smaller file server (500GB) this weekend so any additional info would be greatly appreciated!

Never thought to export the shares via the registry, thanks for the tip! Also these are separate VMDK's that are purely data drives and do not have any programs or OS files on them.
Awesome. You shouldn't have any issues, the registry method really makes the process go even faster. Just make sure to do a NET STOP and NET START on the Windows "server" service from the cli to get the shares/permissions to populate on the new box without rebooting etc. Should limit your downtime too.
