CallManager Upgrade from 6.1.(3b) to 7.1(3b)

We are upgrading CallManager from 6.1.(3b) to 7.1(3b) and have two questions about the process:

1)  We have received a 7.1(3a) "System Installation" disk from Cisco

    In addition I have downloaded the USCInstall_UCOS_7.1.3..sgn.iso file from the website and burnt an IOS DVD

    Can we upgrade by inserting the USCInstall_UCOS_7.1.3..sgn.iso  DVD into the drive and go directly from 6.x to 7.x

    or do we need to first use the disk from Cisco, upgrade to 7.1(3a), then run a second upgrade to 7.1(3b)?

    As I understand it a major upgrade between trains requires a disk from Cisco but a minor upgrade with a train

    can be done by downloading an update from the Cisco website.

2) The upgrade guide recommends disabling Extension Mobility prior to the upgrade.  This is a large Call Center

    where agents use Extension Mobilty.  I know they will not be able to log in or log out during the upgrade but

    assume they will not be dropped when EM is disabled.  We're thinking about disconnecting the Publisher from

   the LAN and upgrading it seperately - leaving EM enabled on the Subscriber to minimize the interruption in the

   Call Center. Any thoughts? Thanks

Hi

1) According to the Compatibility Matrix (http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/ccmcompmatr.html#wp43011) you can go from 6.1(3b) to 7.1(3b) direct, so you can use your downloaded ISO. You'll still need to register the PAK from your physical 7.x media kit to get the upgrade license.

2) I've seen what you are referring to, and I even had a TAC engineer tell me to log out all users and disable EM when I had an upgrade that failed... it turned out to be something else entirely, and I didn't log anyone out or disable it. In fact, I've never had to log anyone out or disable EM to do an upgrade.
