upgrading mdc G5 xserves

I've just finished upgrading/replacing our two mdc G5 xserves with new intel xserves. Both of our new xserve machines are running the latest version of Snow Leopard and Xsan. Both mount our Xsan volume with no trouble but I can't seem to see or add these new machines in Xsan Admin. Because our facility is being used 24/7 and the xsan volume is always running I'm hosting the volume on our legacy G5 system and attempting to add the new intel xserve machines from xsan admin on the G5. CVADMIN recognizes the new xserve machines as ADM but when I try to use the Xsan Admin app on the new machine it won't let me see or add the new machines. Has anyone made a similar changeover from G5 xsan 2.1.1 to intel 2.2.1 and how did you do it without taking the xsan volume offline? Any insight or suggestions are greatly appreciated. Thanks.

Xserve, Mac OS X (10.6.4)

You added the new intel Xserves as clients or controllers? cvadmin reports correctly, and Xsan Admin incorrectly?

I would remove old failover MDC from the Xsan and install new intel Xserve with 10.6.4 with 2.1.1 (not 2.2.1). Add it to the Xsan as client, promote it to MDC, switch the failover priority to make new Xserve main mdc. Then repeat the procedure to replace the other Xserve PPC. After making sure you can failover from one new mdc to another I would upgrade Xsan to the latest version.
It looks like it is to late for this procedure so you may try to stop xsan (cvadmin), all of the clients, backup mdc and primary mdc. Then turn on primary mdc, start Xsan volume, turn on backup mdc and clients.
