we have 2 UC clusters:
The 2 clusters are interconnected by ILS and Inter-Cluster Peering.
Furthemore, we have several Jabber 11.9 clients on both the clusters.
Now, we have to migrate some Jabber clients from 10.5 cluster to 11.5 cluster.
We know that the Jabber client caches the service discovery, so if we change the "Home Cluster"on the User Configuration page of both the CUCM (i.e., we uncheck the flag on the CUCM 10.5 and we check it on the CUCM 11.5), the Jabber client that we want to migrate still connects to the 10.5 cluster.
The only way that we have found to make the Jabber client connect to the 11.5 cluster is to make a "Reset Cisco Jabber", but doing so we lose all the chats, the recents, ...
So, is there a way to force the Jabber client to make the service discovery again, to be able to connect to the UC 11.5 cluster, but without losing all the information?
TIA and regards.
