Migrate to from 2.4.8.0 to 3.4.0.4

Good morning,
Happy New Year 2024 to all members of this forum.
I am using OJS version 2.4.8.0, and I would like to migrate to the latest OJS version 3.4.0.4 since I keep getting notifications asking me to migrate. The real difficulty is that the journal is quite supplied with data. So I would like to know, how will I upgrade without losing my data? Would there be a conventional procedure to follow for this migration? Your contributions will be welcome.
Best regards

What application are you using?
OJS Version 2.4.8.0

Hi @ANKY_Raugland,

We have some comprehensive documentation on upgrading to OJS 2 to 3 here: https://docs.pkp.sfu.ca/upgrading-ojs-2-to-3/ - this may be of some help.

also keep in mind that you first need to upgrade to 3.2 - see https://docs.pkp.sfu.ca/dev/upgrade-guide/en/#upgrading-from-2x
