Hi iRed team,

I am running this iRedmail server for the last few years, since 2018. It is running well without any issue so far. This is a home setup with 5 email accounts.

Now I want to migrate this to newer version but based on Docker for easy version upgrade later on and ease of installation. I want to use Ubuntu 22.04 as the hosting server.

Can I please know whether there is a document describing the migration steps?

I am comfortable with docker and looked at here https://github.com/iredmail/dockerized and https://hub.docker.com/r/iredmail/mariadb I understand this is a BETA EDITION but it works well

I would like to know what are the folders to copy for email migration to new server.

I see my email stores are in folder ":/var/vmail/vmail1/<domain>" and I would like to know whether I should copy only this folder for emails to migrate to new server.

Should I map like this after copying the email to "/var/vmail/vmail1"?
"iredmail_mailboxes:/var/vmail/vmail1"

Any other details on docker based installs will be great to know.

Awaiting your reply.

Mathew
