upgrade CUCM 8.5 to 10.5 using PCD simple migration

panjwani80 · ‎09-25-2014

Hi,

I have a small customer with CUCM 8.5 Pub and Sub. Pub is located in the DC and all the phones/gateways are registered with Sub at the office. I am using PCD simple migration process so no IP address change.

PCD simple migration is a three step process:

1) Export the data from Pub and Sub

2) Shutdown the production Pub and install/import configuration into new Pub 10.5.

3) Shutdown the production Sub and install/import configuration into new Sub 10.5.

My question is if I put a "pause" after step 2 it should not caused any outage up until that point right because all phones and gateways are registered with Sub onsite?

Thanks

Aamir

Hi Aamir,

You need to follow the procedure as documented in the "Migrate Cisco Unified Communications Manager to Release 10.5(1)" section of the PCD Deployment guide here

Correct - no impact to the Subscriber until you proceed with the upgrade.
