GroupWise to Zimbra Migration Tool - Crashing

[eswing]

I received the GroupWise to Zimbra Migration Tool V7.0.1.74. When I am running a migration against an account it will tend to crash on a large mailbox without warning and without producing a log.

Does anyone know if there is a limit on the mailbox size that the tool can handle? Is there a way to figure out why it crashes without a log file?

I never had the chance to use the migration tool since my customer's LDAP was shot. I had success using imapsync, just look for the proper switches you need. You'll just have to keep testing until you get it right. I was able to get around large mailboxes but some large attachments gave me problems. It was crazy since the previous system had no restrictions and I found attachments several hundred MB in size!
I ran imapsync to pull user info from a csv file and all their mail was pulled into Zimbra no prob.
