Hi Benedict,
1. i want to migrate from my free team to the premium one. should I select all the modules, or site library only?
It will depend on what you’ll need. But normally, importing premade sites from the Site Library will automatically enable all the modules you’ll need so you can skip activating the rest of the modules.
You’ll only need to activate the Site Library module if you only intend to import “Stream”. The importation process will activate everything else it deems necessary. π
2. what should I do before migrating to premium theme, in other for the content in my website to remain intact?
All the post and pages will remain intact. While Site library importation adds in demo posts and pages, it doesn’t remove the posts and pages that are already added to the site prior to it’s importation. π
