I just tried migrating a small sample set of Groupwise accounts (5.0.2 tool, 5.0.3 zimbra server, 7.0.3 Groupwise server) and a significant number of messages would fail to convert. In one case 95 out of 4700 messages failed. And one account completely failed due to "error threshold exceeded." I get the same error if I try to re-migrate the account that had 95/4700 failures.
Is this normal? Or should I be expecting all messages to convert?
Is there a new version of the Groupwise migration tool expected soon?
