I am not familiar with sbs2008, and I do not know about cloning server hard drives.
Someone else set up a server with sbs2008. Now the hd has become full, and support has ended.
What I want to do is add a server with Win2012 Not as a domain controller, transfer all data, take the sbs out, and change the domain to Win server 2012.
I may not be able to do that due to... too much to go into here, but politics.
So as a temp measure, is there a way to clone the hd to another larger drive, and then modify the partitions into the larger space? I have seen that Easeus has a server tool, and there are some others apparently.
Acronis, Easeus, Macrium, etc, all have the option of cloning/re-sizing partitions for single disks.
For RAID arrays, we're going to need more information to see how we can help.
HTH,
Dan
