Migrate to SM on same server
Question asked by Damir Matešić - 11/30/2020 at 5:13 AM
How would be possible to migrate mailboxes, e-mail messages, accounts and domains from another mail system on the same server with no data loss and minimal offline time? Also there is a need for IMAP, DKIM and other related settings.
The old mail server has account passwords in plain text.

So you have 2 different version of Smartermail on the same server?

No, I have a different, working mail server on the system and I want to migrate to SM.

Migrate each domain, one at a time.

For every account in every domain, use the SmarterMail Mailbox Migration tool.

So the question is... how many accounts do you have?

Hundreds would be a piece of cake.
Thousands would be a big big big task.

You could also purchase commercial software to automate the process.

Its easier to do them one domain at the time vs one user at the time.

The question has been asked several times before.
Do a search and you will find the answers.

Its pretty  much like this:
Create the domain on  the new server.
Disable the domain on the old server.
Delete all the content from the domain folder on  the new server.
Copy the content from the domain folder on the old server to the new server domain folder.
Then on the new server reload the domain.  You will need to enable it on the new server and add the fqdn for the domain.  Its all in the general tab for the domain.

You will of course need to handle dns, certificates, etc too.

Just do the search, you will find instructions on how to do one domain or all of the domains on the server.

Heimir, he mentioned that he does not have 2 SmarterMail servers running.

Ah, I thought he had 2 different SM servers running and was migrating to the new one.
Missed that one by a mile :)

If he has a bunch of domains/users he can also use https://imapsync.lamiral.info/
