[cisco-voip] IPCCX 3.5(3) to 4.0(4) Upgrade

Hi,
see commens inline:

There's no way I know of how to run Agent Desktop from both versions
on the same PC. So you will need to leave agents logged into your ipcc
3.5, but they will show up as resources under ipcc4 and you can do
your config work there.
We did create a new cluster in the directory to make sure we have a
clear fall-back path and not mess-up anything in ipcc3.5 as it was
still running in production.

Yup, that's OK, the only issue is if the servers have different size
hdd's (one of ours was newer model MCS) you should install that
smaller one first.

We had all kinds of licensing issues, but mostly because we had to
upgrade to Premium, since Enhanced in 4.0 is not feature comparable to
Enhanced 3.5... :(

The standby needs the same number of CTI ports as the master, and it
creates and register them during installation (server setup)

Have fun and good luck,
