[cisco-voip] CUCM Export

[Nate VanMaren]

It's new(doesn't exist quite yet) that the talked about at a local cisco Event.  It's like a bridge upgrade but the original cluster stays running until you switch to the final version.

Cheers

I suspected this might the case with BAT files between the two. What is a "jump" upgrade?

The formats are different, so you will spend a very very long time fixing the bat csv files between the versions.

You might want to talk to your cisco se about "jump" upgrades, I think they'd fit your situation better.

Thanks,

Hi all,

Have a query regarding building a Call Manager from scratch using a BAT export from another. Basically have to upgrade a 6.1.3 cluster on hardware to 9.1 an VMware. This site is a 24/7 operation using Extension Mobility. To do the upgrade it will need to be in 3 steps.....upgrade 6.1.3 to 8.0.3....backup to VMware....refresh upgrade to 9.1. This is going to cause more outages than the site can tolerate.

My question is can anyone see any issues with taking a BAT Export of the config on 6.13 and then importing it on the a new build of 9.1 with same IP details / Hostname - then making sure all configuration is the same between the two and unplugging old and plugging in new?


1)      I would assume all user / application passwords / PINs would be lost

2)      Possible certificate issues (but as verion 6 doesn't have Security by Default) should be ok?

Anyone done an upgrade like this?

Thanks
Russell
