[cisco-voip] CUCM RAM requirement

[Kevin Damisch]

Doing an inplace upgrade from CUCM 5.x to 7.x, but the servers only have 1GB of RAM and we plan on putting in 2GB of RAM.  I was hoping to upgrade the publisher, then power it down, install the extra 1GB of RAM, then power it back up on the new version.  I'm assuming it will fail though to run the upgrade since it doesn't have 2GB.  So, I would need to power off the servers, install the RAM, power them back up, run the upgrade, reboot again.  Any thoughts on how to upgrade this without having to reboot twice?
