Hello, I maintain 2.4.8 to OJS 3.0. Is it mandatory to upgrade firstly to 2.4.8.1 and then to 3.0?
Thanks

You can upgrade to 3.0 from any of the 2.4.x releases.

=====================================
Upgrading from OJS 2.4.x
=====================================

OJS 3.x is a major rewrite of Open Journal Systems, introducing numerous new
concepts and different approaches. The upgrade process from 2.x to 3.x does its
best to adapt old content to the new structures, but we strongly recommend
performing a test upgrade and exploring the new system before committing your
content to the upgrade. Downgrades from 3.x to 2.x will not be supported.

Upgrading to the latest version of OJS involves two steps:

    - Obtaining the latest OJS code
    - Upgrading the OJS database

It is highly recommended that you also review the release notes (docs/RELEASE)
and other documentation in the docs directory before performing an upgrade.
