Hi we are upgrading our call manager servers from 7.0.1 to 8.0.(3a). Ii would like to know the following things.
1.Is there any settings that are not carried over to 8.0(3a) from 7.0.1 after the upgrade that I need to be aware of. For example
Services? AD Integration PIN and Passwords Translation Pattern Gateway configs.(H.323,MGCP,VG224 etc) Sip Trunks Route groups MoH files etc.
2.If people already logged in to the phone using extension mobility before the upgrade. will they still be logged in after the upgrade or logged out?
3.Do i need to upload the feature license for 8.x before the upgrade or after upgrading to 8.x i need to upload the feature license? If i upload the feature license after the upgrade then my Call manager service will be down till i upload the feature license? How should i make sure that my call manaager service is running straight after the upgrade?
2. You don't need to log users out, and the current logged in status is maintained.
3. I usually add the license after the upgrade. 90% of the installs I work on are multi-server, so the publisher being offline for a short while is not a problem (no active registrations). Also consider that if you only have a single server, it will still take a few minutes for phones to update firmware, so you have time to upload the license. I would certainly register your upgrade PAKs on the Cisco license portal before doing the upgrade though.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
