HD Controller Migration

I have been running Rockstor for about a month now using the on board sata ports for my MB. I like it alot and decided to move some other storage to Rockstor. My question is when migrating to a stand alone controller will I have to do a reinstall or does Rockstor store the UID for the drive pools so that no matter what sata / sas slot is used the disks get put in the proper pool?
