Very interested in this as we're about to do the same thing in the next few weeks. We have two linked mode vCenter servers as well.
My slightly different issue is that I need to keep VSC running on one of the vCenter servers (it points to our older 7-mode systems that can't use SnapCenter) and run the SnapCenter plug-in on the other vCenter server which points to our cdot resources. Do either of you know if this configuration is supported?
