Yep, we are running into clustering issues...

Getting Inactive: (Remote host is reachable but connection is not established. Either refresh this page, or check the credentials.)

For IMP connection, so MRA is down...

Still looking for a fix...

I’ve done 2 8.11.x to 12.5.5 fine (clustered setup, 4). There is a bug with clustering to watch out for but I did not encounter it. The 12.5 Cisco download page has a note and link about this.

Currently working on jabberd process high memory consumption issue on one node that has been present since 8.11.x which 12.5 had memory leak fix for but still an issue. Slow memory increase over time just on one of the edge nodes.

Going to look over 12.5.6 release notes now....

If that is the case, then I would double check that it is supported. In the release notes there is a chart for supported platforms based on serial numbers. If it is a legacy Tandberg box, then I suspect 12.x may not work out for you.

This is a legacy Tandberg VCS for video only... no MRA, no remote phones... just inbound and outbound sip video...

We’re at 12.5.3 and probably moving to 12.5.5/12.5.6 somewhere in the Holiday timeframe when everything quiets down a bit.

There hasn’t been really any significant issue upgrading from 8 -> 12, but there have been a couple of bugs that largely are all resolved by deleting and rebuilding whatever the thing is that is misbehaving.

The requirement for the _cup_login and _cisco-uds SRVs went away though it still endlessly logs a warning about not finding them, but it will work.

You do also gain the ability to play with the openssl cipher strings but in my limited experience trying to change those to bump them up a notch, it ends up breaking XMPP or something.

Thanks, the latest is 12.5.6, released last week, I am avoiding it like the plague...and the bug fix doesn't apply to us.

I am going with 12.5.5 (released in August).

I already have release keys (Cisco AM sent them over)...

Hybrid services are on a separate VCS-C that is already 12.5.

My plan is to get new certs if we have any issues


Thanks!

A couple of thoughts for you...


  *   Get the software release key for 12.x now (you'll be asked to enter it during the upgrade in the GUI). You'll need to work with TAC > GLO for this if (and I assume this would be your case) the existing 8.7 serial is active in Cisco's licensing system. The caveat to trying to do this with Cisco's self-service license re-host tool is that while the 8.7 serial is active, it won't allow you to assign the new 12.x software release PAK to the serial because the serial is already assigned to another software release key.

     *   Take a backup first, your only roll back option is to re-install 8.7 and restore the backup.

  *   Your VMware Hypervisor needs to be 6.0/5/7.

  *   If you have Hybrid Services configured, make sure the management connector is up to date first.

  *   SSL Certificate validation changed a bit in 8.8+

     *   Verify proper forward / reverse DNS for all the relevant touch points
     *   Make sure the Expressway certificate trust is up-to-date with all the current CUCM,CUC,IMP identity certificates (self-signed) or CA certificates (public CA signed certificates).
     *   no duplicate certificates in the Expressway trusts
Beyond that, just pay attention to the caveats list in the upgrade doc for your version of 12.5.x (12.5.4 is the latest I think).

Thanks,

Ryan

Can we just upgrade directly or do we need to go to an intermediary version first?

Also, any gotchas besides new certificates?
