I have two windows servers 2000 and 2003 with ATA storage (1 disk) each and I want to upgrade both to windows server 2008 r2 with raid 5 storage. I want to migrate all my settings/data to the new server units. Can someone guide me on how to achieve it? I have new servers with 3 disks each in preparation for the raid 5 setup.
As much as possible, I don't want to shutdown my two servers when updating/migrating to a new setup as I can't afford to have a down time. I would appreciate any help.
