TSFARM is still accessible, however, you are still able to access any data that you saved there from your local computer!
There are newly mapped drives on your local PC environment which you can find as shown below (this is not the case if you are working from home, so please use TSFarm instead):
You also have a new local home folder (H:\ drive) which will be synced across all office computers, so you can access documents saved there wherever you log in (i.e. in meeting rooms).
Z:\ is the TSFarm user drive where you can find Documents which were stored under the U:\ drive on TSFARM. This includes your TSFARM desktop files, etc.
If you have any issues, please create a ticket through the intranet (only accessible through TSFARM) so IT support can help you.
