Upgrading OJS while using custom theme

I’m using OJS 3.4.0.4 with a modified version of the Booststap 3 base theme. I’ve applied lots of modifications to the base theme and now am wondering if I upgrade to the latest version of OJS and something goes wrong, will I be able to revert it to the version I’m using now?

Hi @GSI,

Before upgrading you can run a test upgrade: make a copy of your installation in a subdomain, for instance, and check if everything is working as expected. Regarding your theme, you’ll loose all your customization if you upgrade it.

Best regards,
Josh

Thank you Josh, then I guess I’ll stay in the current version
