We're currently running CUCM and IM/P 10.5 and going to be moving from the IM Address scheme "userID" to "Directory URI" since Jabber 10.6 now supports Directory URI lookups on UDS.
Question is...when I migrate over to Directory URI, will their buddy list for internal contacts automatically be changed over to Directory URI when they log back in?
Did you ever get around to attempting this? I tried this last night with a customer and I had to failback to "UserID" because I was noticing and erratic behaviour in how users JID was being presented.
I transitioned from a jid made up of "samaccount"@company.local to a JID consisting of the DirectoryURI field. What I noticed after making the changes outlined in the URL below.
A lot of users JID got updated just as they should be to match their directory URI, but a lot also got updated to be "samaccount"@emaildomain.com which of course is not valid and those users showed no presence, yet they could login just fine.
To resolve the presence status issue, can try to add below lines in your jabber-config.xml file:
<?xml version="1.0" encoding="utf-8"?>
The above is an example where LDAP synced using "mail" attribute.
