I want to upgrade a moodle website currently on version 2.5 to the latest version.
I need to clarify that is it possible to upgrade Moodle 2.5 directly to Moodle 3.3.
OR
As mentioned in the moodle upgradation document "Note: You can only upgrade to Moodle 3.0 from Moodle 2.2 or later. If upgrading from earlier versions, you must upgrade to 2.2 as a first step." I can only upgrade to Moodle 3.0.
Please confirm.
Thanks in advance.
I can say that I have actually upgraded Moodle 2.3, and Moodle 2.5 successfully to 3.x, though not 3.3 specifically.
That being said, you have to also take the following considerations:
If you aren't sure of any of these, I would go grab a Vagrant/VirtualBox/Docker setup of Moodle, stage your current site (i.e. install it with the same software you have installed on your production server), and upgrade it locally to ensure everything goes as planned.
