Merging email between servers

Post by Elpamba »

Hi,
while upgrading zimbra to version 9 which had all our email till February there was an issue. So a fresh install of email was done on another server which based on an email backup upto 2019. Now it's being used as production. We have used a mailbox migration script to move mails to the old server . Now they're are 2 challenges :
1.Duplicate mails exist. Is there a script to remove duplicates?
2. Unable to determine if all mails have been migrated as we are still getting reports of email that can't be traced. Is there a script we can use to identify emails in lobe server that aren't present in the other and export them?

Hi, for question number 2 (and partially number 1) take a look at imapsync:
