I have about 1000 Gsuite accounts and now want to migrate to Zimbra. Each mailbox now is about 10GB.
Could you please share the best way to do migration?

Many thanks.

I would suggest to go for IMAPSYNC. It is very easy to install and an excellent tool for migration. I personally migrated from G Suite to Zimbra, Postfix/Dovecot server to Zimbra. Please check below links for installation reference.

Thank for your comment. Could we migrate account with password from Gsuite to Zimbra?

Hi zimico,

(sorry for the late post, this answer somehow got stuck in forum moderation)

such a migration would be feasible under our new cooperation with Zimbra (

Note that an imapsync-based approach will typically include only emails, while we can also migrate contacts/calendars/tasks/(files) and certain settings to Zimbra.

Note that for your project size, there might be special pricing/discounts available.

We're also happy to provide you with some free migration codes for prior testing upon request.

Thanks and best,
Hans-Jörg (audriga)

Prepare the Source Environment
Export a list of users to a CSV file.
Inform users to split up folders with a very large number of items.
Ensure that you have admin credentials available for use during migration.
Test mailbox access.
Make sure the necessary ports to connect to the Zimbra server are open.

Hi, I have a question about migrating gsuite to zimbra

Is it posible to make email get in to 2 mailbox? zimbra & gsuite

My case is some users want to migrate to gsuite, the others want to stay in zimbra.

I have already setup a gsuite and register some account using domain same as in zimbra.
