I have a question regarding a large multisite project. The customer has several pages that share the same user right, the media, some content and the users. But they have different themes and some of them have modules that only this specific sites uses. What's the best way to "port" all of this to a new Drupal 8 project?
I think that I have to use multisite so that the different pages can have their own themes and modules. And I can have modules that all pages share. Am I right with this?
But what do I use to share users, content, taxonomy, media and user rights? And what about the database? Can I have everything in one database or do I have to use different databases?
