We have recently built a CUCM 6.1(2) Cluster in the Lab using the output from the DMA Tool run on a Customers CCM 4.1(3) Publisher as part of an upgrade. The migration from the CCM 4.1(3) cluster to the CUCM 6.1(2) Cluster will be a phased migration and once the CUCM 6.1(2) Cluster is installed, Inter-Cluster Trunks will be set-up between the two Clusters. The new CUCM 6.1(2) servers have new IP Addresses and Hostnames.
The new Cluster appears to be working fine under test except we have found one issue as described below:
The Service URL's seen in User Device Profiles for Extension Mobility for instance contains an IP address from the CCM 4 Cluster. When the EM login Sevice is attempted the attempt obviously fails as the CUCM 6 Server has a different IP Address.
So far the only way we can see to get round this is by logging into the Users "User Web Page" and un-subscribing then re-subscribing to the EM Service.
A simliar situation exists for the Users Personal Address Book.
Can anyone suggest a way of getting round this rather than having to login in as every User and un-subscribe then re-subscribe to the required Services ?
