WLC 5508 HA RMA Process

Question

Hi all,
I am currently in a situation where our primary 5508 failed, our secondary 5508 took over, and we RMA'd the primary. Now that I have received the primary RMA device, I am stuck with what to do with it. I know that I need to transfer the licensing and have found documentation on that but what does the rest of the process look like? Do I just plug it back in using the redundancy port and away we go? I assume there are additional steps but I am having trouble finding documentation on it. Please help! Thanks in advance,
Derek

Thanks Scott. After a few mishaps I figured that this basic config involves:
- Recover-config and reboot
- Enter the correct management address, subnet, VLAN tag, LAG parameters as the former primary unit and the rest can be garbage? -> reboot
- Login and enter:
      config interface address redundancy-management IP1 peer-redundancy-management IP2
 config redundancy unit primary
      config redundancy mode sso         (doesn't seem to be sso AP option in this version - 7.6.130)
- Reboot and either power off or wait for boot then power off
- Connect up heartbeat and management cables and power on
- Wait for sync...
however I experienced an issue where it got to "Found the Peer. Starting Role Determination..." and then would get no further after waiting 15minutes.
Should this be a fairly quick step? I then rolled back and put my old primary in the same way and ended up waiting about 30mins and finally it worked. I realised after the fact that when I put the new primary in I hadn't set the LAG correctly and I also did not give it the exact same management address so that might have caused trouble earlier, but I can't explain why the old primary took so long either.
