Thanks for your reply as always fsiegel
We jumped from 5.0.18 -> 6.0 and this problem is with 6.0. By the way; When I enter the zimbra server information on the migration wizard I get an warning that the migration wizard on the server is newer than the one i'm using. I have doublechecked that it is the same version as on the server (6.0) but is still get this warning. Related?
