My thought was to do an install on a new server for the 5.1 publisher node
w/new IP Address and restore the DMA data file onto that, thereby not even
touching the 4.1 publisher (other than running DMA). Would also leave 1
subscriber node from the 4.1 cluster alone, and upgrade the others and point
them to the new 5.1 pub. Just not sure what would happen having two clusters
with publishers having the same host name (maybe no problem?)
