 From what I've seen, migration seems rather impossible, since LDAP was 
abandoned and the switch from Postgres to Mysql. We've the same problems 
like you have, and switching over today is close to impossible...

Very nice product, but without an upgrade possibility, we could also 
start reevaluating the other groupware suites on the market.
