Upgrading from OJS

Hello, this is my first topic here.
I’ve got a question: I need to use again an old OJS installation (version I made it in 2010 and I haven’t used it for many years, but it still works online.
Is it possible to upgrade it to a new version? If yes, which one?
Is there a guide to read to do this?
Thanks in advance.


Hi @antoOJS,

You can upgrade from OJS 2.2.x to the latest 2.4.x using the upgrade scripts; see docs/UPGRADE in the new version’s installation package.

If you want to upgrade to OJS 3.x, you’ll need to upgrade your old 2.2.x to a newer 2.x first. The OJS 2.x to 3.x migration only works for 2.4.x. See docs/UPGRADE-UNSUPPORTED in the OJS 3.x package for details.
