Topic: Upgrading Debian 11 server to the latest version

iRedMail version: 1.6.1 MARIADB edition.
Linux: Debian 11
Store: Mysql
Web server: Nginx
iRedAdmin-Pro

Hello,

I need to upgrade my Debian 11 server, which is currently running iRedAdmin-Pro.

What is the correct procedure for such an upgrade? Is it sufficient to perform a standard OS upgrade (Debian 11 -> Debian 12 -> Debian 13), or are there additional iRedMail/iRedAdmin-Pro specific steps that need to be taken?

My main priority is to keep all current configurations, settings, and mailbox contents intact, ensuring the transition is as smooth and quick as possible.

I would highly appreciate your guidance and advice on this matter.

Re: Upgrading Debian 11 server to the latest version

FYI
https://docs.iredmail.org/upgrade.debian.11-12.html
https://docs.iredmail.org/upgrade.debian.12-13.html

Another upgrade path which is highly recommended since you own a valid iRedAdmin-Pro license, and it's qualified to get an iRedMail Enterprise Edition ("EE" for short) license for free. FYI https://forum.iredmail.org/topic20762-a … omers.html

- Migrate to EE on current Debian 11 in place.
- Upgrade OS release to Debian 12
- Login to EE as global admin, click `Deployments` -> `Re-perform full deployment`, to generate configuration for new software offered by new OS release. You may want to run for several days to make sure all services are working as expected.
- Upgrade OS release to Debian 13.
- Again, login to EE as global admin, click `Deployments` -> `Re-perform full deployment`.

No need to update config files manually in this case since EE handles all for you.
