Hello SharePoint Team,

I developed a new version of SharePoint list, so I want to set older list as Read only mode after 2 AM . So is there any way to do it?

    list.BreakRoleInheritance, then update all the roles to only have the read permission.

  • list.BreakRoleInheritance? What is this? I haven't use any programming code to build it.

    If you don't want to use the API then you can manually update all permissions on the list to be read only.

Just as an option, you can use Flow/PowerAutomate to reset permission on schedule.Use the trigger schedule-recurrence. Still you will need to call Http service to use API, here is an tutorial.
