Windows to Linux migration prerequisites

[steikebiffen]

Hi,

I've read the migrating from Windows to Linux documentation, but I am confused around the prerequisites. If someone could help answer these three questions, it would be of great help.

In my scenario I have Windows 3.2 OTRS with a mysql database.

Q1: Do I need to upgrade 3.2 Windows OTRS to 3.3 before migrating?
Q2: Does the Linux-side OTRS version in a migration scenario need to be the same version for the migration to work?
Q3: Does the Linux-side database-server need be MYSQL to migrate the Windows MYSQL-db using the CloneDB script?

Thank you

Hey there,

I've never done such a migration, but the migration has to be done from the same major version to the same major version. That means you should either (!) upgrade on your windows machine to 4.latest and install that version on the linux server, OR (what I would recommend) install your current version on linux and upgrade to 5.latest.

To migrate it should be enough to create a fullbackup and restore that backup on the linux server (taken all perl modules etc. are installed).
You also should be able to simply switch from MySQL to MariaDB if that is your desired database.

It's probably (probably means that there's not a big reason not to) safe to install 3.(n+1).latest or if n=3, 4.0.latest on destination, then follow the steps to restore database, copy Config files, and continue UPGRADING steps.
