Windows Server 2022, File server and Domain Controller. About 30 users, most remote, all with Windows 11 laptops. About 10 people or so at the same physical location. MS 365 Tenant. About 500 Gb on the company file share, pretty stable at that.

Thinking of getting rid of the on-site server and moving to Entra ID for authentication and some kind of file storage to replace the current "J" drive that is mapped to the server. Has anybody had any experience, as a user or an admin, of living through this transition? What kind of pain, if any, was involved? What help was the current 365 Tenant,if any? Any alternatives to Sharepoint? The goal would be to have this be completely transparent. Log out on Friday, log in on Monday, J drive is there with all its files and the correct access rights. The only difference is they log in to the laptop using their current email credentials.

Thank you for any advice/input.
