Putting an entire Google Workspace organisation's Google Drive accounts into read-only mode

[Martyn_Drake]

Hi,

My employers need to copy the contents of everybody's Google Drive to another cloud-based platform.  We don't want users to make any changes while we make the copy.  The only thing I can find relating to this is file locking via Google Drive API - but is there any other method in which to disable user's write/delete access to Google Drive for a short period, but still allow the tool (which will presumably be using Google Drive's APIs) to copy the data?

Many thanks,

Martyn
