RAID 5 migration not work

[revaaron]

I had
1) 1.5TB standalone
2) empty
3) empty
4) 500GB RAID 5
5) 500GB RAID 5
6) 500GB RAID 5

then I broke, removed and reformated the 4,5,6 RAID 5.
I put another 1.5TB in HD2 and started migrating 1&2 to RAID 1.
Which is is migrating to right now.

Now, I'm trying to get the 4,5,6 RAID 5 back, but when I go to the migration page, then to the add drives page, I click "migrate" and it brings me right back to the same page.

My guess is that it won't do two operations at this level at the same time.
