I ran into a snag.

Dell Prosupport helped me figure out how to best expand my storage on a single tower server box running 4x 250gb drives in RAID5.

So, MBR and BIOS is what I have on SBS2008 running Exchange '07.

Got 4x new 1TB drives from Dell, backed up, pulled drives, slid in new ones, rebuilt raid, loaded driver for external backup drive and restored. Awesome. Oh wait, I can't expand the volume or affect the other available space.

So I need to convert it to GPT.

I am reading about nightmares, NO and DON'T when it comes to backing up an MBR volume and restoring to a GPT disk. So how do I go about this?

Here's two plans that I'm looking for feedback on...

PLAN A) Nab two spare 2TB external 3.5" drives and slot #1 into my quick dock unit. Do a full backup to the official Seagate backup drive used for the native NT backups. Then make a clone of that Seagate drive. Safely stash the clone.  Disconnect the seagate drive. Then slot #2 drive and reformat as GPT disk. Setup NT backup to complete a full backup to the #2 drive (now GPT) and give it a try. If successful, Then wipe existing RAID5, reformat as GPT and switch BIOS to UEFI. Restore from #2 drive.
If fails, wash rinse and repeat but switch back to MBR and backup from official NT drive to properly restore.

PLAN B) Buy a QNAP 4 or 5 drive NAS (Which I have been wanting to get for failover, space, etc.. anyways) and backup the volume there in a GPT partition. Partition? vPartition? Here is where I'm lost. How to make this work with a NAS? I havn't takled to QNAP yet to find out if I can build a RAID as GPT in their box.

I've already dug around the Acronis product and it has severe deficiencies when it comes to GPT according to their website. The product they specified for me is the Backup & Recovery 11.5 Advanced SBS edition.

I just know that with one box.. I need to make sure that I have adequate solid backups to restore from. I don't have other test machines and especially none with the H700 controller.

Open to any and all criticism, feedback and recommendations. Oh, and I will not be using freeware for anything on this project.
