Migrate from shared folder to groupfolder

Hey there
I hope you can answer my questions.

I’ve set up Nextcloud with only one usergroup and a shared folder to that group.
Now I want to copy all files to a groupfolder, because i’ve read of the adventages in many forums.

  • Is there anything to consider, when I copy the files?
  • Will it work, when I only drag & drop the content of whole directory into the groupfolder?
  • Will the shared links remain?
  • It’s very important that everything works and it would be great when the users didn’t notice anything of the change. Is that possible?

Nextcloud version: 15.0.7
Operating system and version: Ubuntu 18.04
Apache version: 2.4.29
PHP version: 7.2

Thank you for your support!
