Live restore large volume to new OS on different server?

Here's the scenario, I want to see if I'm thinking straight here:

I have a file server with a very large data partition of almost 5 TB.  It's running Windows Storage Server 2008 and getting low on physical space so I want to move the data to something more modern, specifically Server 2012 R2. The server name needs to stay the same as the old one because our document management software depends on UNC paths and it's not easy to change.

My plan is to create a new 2012 VM on different hardware, turn off the existing 2008 server, name the 2012 server the same as the old 2008 one and assign the same IP, and install the RR agent.  Then I'd kick off a Live Recovery for the data partition, thereby keeping downtime to a minimum so users can access the data even while it takes days to restore.  Is there any reason that would not work?

Assuming that plan works, what happens after the restore? Does RR take a full base image of this huge server, or is it smart enough to know only the C: drive changed and the D: drive is just an incremental backup?

Thank you in advance for any thoughts and advice.

  • As long the data partition was on a different volume than the system volume, you can do a live recovery of just a single volume. You will need to have the 'new' target volume be the same size or larger than the one that it had been on (with a VM even if you won't use the whole thing, just make it larger and thin provision it). Also for live recovery you must use an agent (you mentioned that, but just to clarify you will need an agent). The other 2 suggestion (Emte and Corrigun) are spot on, but you do have options and RR is one of those should you choose to use it. Works just fine, matter of fact that almost the text book idea behind the Live Recovery option.
