My client has an old SharePoint 2010 farm that we plan to shut down soon. Users have created Access applications that are connected to SharePoint lists. Some of these are very old and not stored on any SharePoint server. I've sent multiple emails to the users asking them to request data migration, but no one has responded, yet I see in the Audit logs that these lists are still being used. I suspect they are not even aware that the Access app they are using stores data in the SharePoint lists.
I have two questions about this:
When I lock this farm, what is going to happen to the Access applications? I found some articles on the Web that warned about Access data being corrupted. Has anyone done this before? Any idea of the risk?
Is there anything that I can run to find the Access applications in use? I have already run PowerShell against the SharePoint farm, and the Access apps in question are absolutely not stored in the farm or on the servers themselves. There are many shared network drives in use so I suspect the Access apps are there.
I can reach out to someone on Networking if necessary and ask if they can run something against other servers/shares to find the databases. Does anyone have recommendations about this?
Thanks in advance!
