HDR RSS reshuffle

IDS 11.70.FC7GE we have a HDR primary and secondary (ro) configuration in place. In prep for this weekends hardware migration I established a RSS server on new server1 and went to establish RSS on new server2 but RSS on server2 would not initialize , evidently with GE you can only license 2 nodes in per cluster. So, what I want to do is take the current HDR secondary out of the cluster and make new server2 a HDR secondary (or server1, which ever is easier). On the primary : onmode -d standard ? On the secondary: onmode -d standard ? On the current RSS (new server1) : do nothing. On new server2 (currently in fast recovery) establish it as the HDR secondary. However not sure if I issue the onmode -d standard on the primary that this will not only break HDR but also the RSS to server2. Since moving the archive files to the servers took a year and a day, need to make sure this will work as tomorrow is the cutover day. Any recommendations/suggestions welcome. Thx. Mark
