The normal way to do this would be to simply insert the two 3 TB drives into slots 4 and 5. There is no technical need to "migrate", or to put the 3 TB drives in the first two slots. The migration approach rebuilds the array needlessly (and isn't quite as safe, since you lose redundancy when you take out the existing drives).
If for some reason you want to do the migration, you should be able to. Though it might be safer if you delete the partitions on the old 2 TB drives (using your PC) before you reinsert them. Occasionally you might see a "corrupt root" if you reinstall a disk that was previously used in an a readynas.
Also, with Xraid2, the redundancy is spread across all the drives, so there is nothing uniquely "redundant" about drive 2.
