User Case: Migration Tool for NAS to SharePoint Online

“I have a requirement to migrate files from Synology NAS to SharePoint Online. Can please someone suggest a migration tool? Does the migration tool take into consideration the permissions based on how it is assigned on NAS for every user?

Finally, the total files on NAS are around 200k combinations of files and folders and when the library is migrated to SharePoint, they want to proceed to upload files/folders and assign permissions to users. Will anything stop them from performing those operations?

Any suggestion/advice is highly appreciated based on the concerns mentioned above. Thank you!” – A question from StackExchange.

SharePoint Online is a service on Office 365, which allows users to make collaboration with others in a hassle-free way.

  • Top Security. Office 365 is the most secure and is almost certainly more secure than most companies’ standard firewalls. So does SharePoint Online. Contrastingly, NAS devices would be attacked by natural disasters and hardware failures.
