There should not be licensing issues.  Even the mere act of changing controllers and drives should not be enough to kick off activation again.
I have a Dell T310 with SBS 2008 that I plan to upgrade from an S300 controller to an H700 controller.  I plan to:1.  Mark and pull the current drives and S300 controller.2.  Install the H700 and set up a 2TB disk as a RAID-0 and restore to it to make sure the backups work.3.  Remove the 2TB drive and set up the disks in a RAID-5 on the H7004.  Restore. Question:Will ther e be any license issues with the SBS 2008 restore? Thanks!
Any license issues after restore?
