If the WAN has been down for some time most likely the subscriptions <BR>
would need to be reinitialized anyway. I doubt the reboot is going <BR>
to break it much more than a planned power outage would.<BR>

down. Who knows what the SQL subscriptions would do. And I've noticed <BR>
they do not come back gracefully after a disconnect.<BR>
<BR>
Wait until the WAN is up and communications is in full swing before <BR>
attempting any work.<BR>
<BR>
That's my conservative 2cents worth.<BR>

Does anyone else have opinions on this? Please help to put my mind <BR>
at ease. The second sub is in NY. The pub and first sub are in DC. <BR>

These are only operating system upgrades and service releases - going <BR>
from 4.2 to 4.4. We have a publisher and subscriber in our main <BR>
office, and a subscriber in our second biggest office. Our third <BR>
office is an SRST site.<BR>

If the WAN is only connecting remote offices, then you should be <BR>
okay. If all your CallManager servers are in the same building you <BR>
are fine. Any remote phones will upgrade firmware once the wan is <BR>
back up.<BR>

QuickQuestion<BR>
<BR>
<BR>
<BR>
We are planning to upgrade the base OS and patch one Publisher and <BR>
two Subscribers this Saturday night. All of our building power where <BR>
our servers reside will be "on", but our WAN circuits come into our <BR>
complex in an adjacent building where the power will be shut down for <BR>
up to 12 hours. Assuming that the WAN circuits will be dead, should <BR>
we go ahead and load the software or should we wait until the WAN <BR>
circuits are fully operational? We normally load the Pub/reboot and <BR>
then load the Subs and reboot after each new piece of software is <BR>
loaded. Please let me know if there can be negative repercussions. <BR>
Thank you!<BR>
