This step won't be necessary in coming versions above v4.4 as we are working on improvements. However, if you are upgrading your V3 site now, you can do the following to clean up unnecessary files after you upgrade the site.
I've tested this myself on a v3.8 upgraded site and things went fine for this method. If you have v3 third party modules on your site, you want to disable those before upgrading anyway, but if you didn't follow that advice before upgrading you will want to load those module/ files into the PF.Base/module folder. However, advice is always to disable until you check with the third party developer to see if they work in v4. |
