Hi to All.

I have been testing the migration of a Cyrus Imap Mailbox in two different ways:

a) Using imapsync
b) using thunderbird and moving mail folders directly

I found that option b is really faster than option a. Also verified that the mails respect original dates, status, etc.

We are less than 30 users, and we plan to take users to zimbra by smalll groups so doing the b way is good for us, as we can revise the migration directly with the user, and most of our users already uses thunderbird.

Is there any drawback for using option b instead of a, that I could have not noticed?

Many Thanks
