<DIV><BR></DIV>My question, to which I dont have an answer but i'm sure
someone else on the list does: is there any ramifications to running different
OS levels across your cluster during your upgrade process (assuming several
days to update all the nodes in your systems then at 1 per day) <BR><BR>Also,
which server is your TFTP server, or do you have several. not sure how much of
the phones configurations they store incase they cant talk to a
service.<BR><BR>Personally, i'd be just waiting for the rest of the cluster to
implode that same day... murphies law and all that :) <BR><BR>
