    Tried to acquire the information from other posts, release notes and documentation but I couldn't find anything about requirements or possibilities of supported version to upgrade from/to.

    My main interest is of upgrade from to 3.2.3 directly. Is it necessary to upgrade to 3.1 first? Was it tested at least in lab environment if it's even possible? For refernece, the OS is Debian9.

    Any information/help/guidance is appreciated, thank you!

    This is quite a jump, but it should be possible. It has not been tested by us though, and a lot has changed since then. Make sure you have a good backup and then do the update.

    Please note, for the future, it is best practice to update immediately because quite some releases come with your security fixes - your current setup is very insecure.

    Thank you!

    The instance is an old and utterly customized one, the main pain point would probably be the integration of new services and addons like DKIM or so. Will the installer destroy inplace configurations or will it skip them? The first one would be desired because it can be "fixed" after the upgrade but otherwise the installation will be broken without any chance to rebuild it.

    Let the installer reconfigure services. To be safe, do a force update after first updating with
    Code: --force

    Configs will be overwritten after reconfiguring services, but you can customize them. In the future, use conf-custom templates to modify configurations so you can upgrade easily without having to restore things every time.

    Another option to consider is installing a new 3.2 server and migrating (eg. even one domain at a time if you need to fix website php, etc.).
