[cisco-voip] CUCM Export

[Russell Chaseling]

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
