One problem you might have is that you will have to go into the F10 partition or boot off the Smart Start cd and run the System Configuration Utility and set the 221 as the first boot controller. Save and exit and you should be ready to go.<BR />Nothing needs to be done in advance except for a good backup which is always recommended.

Specifically what problems will i encounter when booting NT after changing the array controller. Do i need to do anything to NT before upgrading? thanks in advance.
