Seems straightforward:

Can I take a RAID5 disk set from my old server and place it into a server with dissimilar hardware while still retaining my existing data.

I know there will be OS driver issues, but I'm only really worried about the dataon the disks.

Any comments? Thanks

I would think you have to move the raid controller too so that the disks are accessed the same way. Be sure to make a tape backup first.

How old are your disks? Do you expect a lot more life out of them? You might be better off making a backuptape and reloading it on the new server anyway (which you seem to want to avoid).

Be careful or you might end up with nothing!

Thanks. I was just investigating the possibility from a disaster recovery point of view. Thanks for your comments.

You can only do this if the controllers are from the same hardware vendor and they are identical in the method used to create the set.

Your best method is to use the tape backup and restore as suggested before.
