Lotus Traveler 852 upgrade error

I will start by saying this shouldn’t happen in most sites.  In Bluewave, we run lab servers with different versions of Domino, Traveler, Sametime, Quickr, WAS etc etc etc and we are most assuradly non-standard setups.  After upgrading our Traveler server (which is also our BES server… again unsupported but works) to 852 it stopped working.  NTSError log files had variations on the following:

The problem was related to the databases in the \data\traveler\map directory, which control mapping of fields.  The Traveler server itself did not have rights to the databases post upgrade.  What caused this?

Replication.  Another server in the domain, running traveler had replicated and screwed with ACL’s.  Re-adding the local server to the ACL resolved the issue, but if you have a large traveler deployment, you may want to look at new replica ids or watching ACL’s post replication.
