Object storage S3 as primary storage - issue

Hey guys and sorry to bump this but I’m curious:

I have a working nextcloud 20 setup (complete with users, files, apps, etc) and want to switch to s3 storage. If I stop all services (LAMP) and sync (rclone) the data folder with my bucket won’t nextcloud pick up from where it’s left?

P.S. I’m not using file encryption as it didn’t play well with some apps.
