I'm upgrading from GW 7.0.4 to GW 8.0.2 HP3.

In my first region I have a 2-node Linux OES cluster. Secondary domain on 1st node and PO 2nd. node. Do I;

1) Migrate the Domain resource to the 2nd node,
2) Install the new 802HP3 code on 1st node, then
3) Migrate the domain back to the 1st node and wait for the 7 to 8 upgrade to take place ?


Do same as above, but down the secondary domain, Install code, and bring back up ?
