We currently store user data, shared applications and other public files on a DFS that sits on our network, currently hosted on two Domain Controllers, although not replicated between the two. This means the front-end GUI (windows explorer) would pull files from both servers to display them in a common environment where users can extract the necessary files.
Since our Domain Controllers performing so many roles, we would like to migrate data from the DFS to a newly purchased and installed NAS device.
I would like to query the online community to decipher the best method for doing so. We have considered creating a replication group that would copy all data from the DFS to the NAS device. Once replication is complete, we would cut all users over to the NAS device. However we are wary of the affect this would have on open data that users may be editing on the DFS while the cut-over is in progress. We thought the best way to accomplish this would be to decide on a window in which users would only store data locally if they happen to be working on any of their files saved to the DFS.
We have also considered creating a script that would perform this feat for us, however I fear that we would run into the same issues with the cutover.
Can anyone suggest a clean method by which we can cut over to the NAS device from our DFS?
