Connection 8.6.2 to 9.0.1 upgrade switch-version failed

[Jason Aarons]

I upgraded a 2-node CXN 8.6.2 to 9.0(1) and the Pub won't switch-versions.

admin:show version active
Active Master Version: 8.6.2.20000-2
Active Version Installed Software Options:
No Installed Software Options Found.
admin:show version inactive
Inactive Master Version: 9.0.1.10000-36
Inactive Version Installed Software Options:

admin:utils system sw
admin:utils system switch-version ?
Syntax:
utils system switch-version
no parameters are required

admin:utils system switch-version

Active Master Version: 8.6.2.20000-2
Inactive Master Version: 9.0.1.10000-36

If you are switching to an earlier release, you must run:

utils dbreplication reset all
from the publisher after all the nodes are switched over.

Do you really want to switch between versions ?

Enter (yes/no)? yes

Switching Version and Restarting the Appliance ...

Switch version duration can vary depending on the database size
and platform configuration.  Please continue to monitor the
switchover process from here.

Where do I find the cuc-version-switch.log ?

Jason,

Use RTMT to pull down the Install logs and you'll see the CUC version switch log.

but when i try in my lab on single cuc server with same version it was working..

as now applying in live cuc cluster it is showing error!

!

!

does anyone have solution for it?

in the 11.x install guide below:

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/11x/install_upgrade/guide/11xcuciumgx/11xcuciumg030.html

Take a look at Table 3-1 Upgrade Matrix for Unity Connection to see that you are running into an L2 upgrade.

then it says this a little further down.

Caution In case of L2 upgrade of a cluster, do not restart or perform switch version on the publisher server before completing the upgrade on subscriber server otherwise cluster does not function properly.

I ran into the same issue.  Both servers need to be upgraded first before switching versions on the pub.  After the pub comes up and is taking calls you can then switch versions on the sub.

Hope this helps

I ran into this same problem, though not upgrading to 9, upgrading to 8.6.2.22900-9 and I followed the upgrade guide to the letter and also worked with TAC.  I believe that upgrades post 8.5 to 8.6 no longer automatically switched version as part of the upgrade in an HA cluster.  The error in the Install.log implied that the inactive version on the Sub didnt' match so it failed to complete the switch version command.

I ran the upgrade 2 times and the error is the same and there are no other errors in the install log.

I would recommend that you review your install as David suggests and also ensure you are not needing an intermediate upgrade of some kind (you're attempting a major to major release upgrade with out any COP or patched upgrade file) first,otherwise I would try installing the version on the sub.

Good Luck,

Jeff

Hi Team

If required cop files installed and DB replication is alright. Then try below method

We have faced similar issue, while switch-over from 10.x to 11.x (Unity)

while utils system switch-version, you get sync error and filed.

sync switch version failed

add following command on pub & sub CLI before switch-over version
utils os secure permissive

then run utils system switch-version

This will resolve the issue.
