Easy answer maybe. A lot of offices can be moved to Linux, or even a hybrid Windows\Linux. The issues come down to cost and growing pains. A transition isn’t free even if using a free version of Linux. You have to consider training cost and setup cost upfront. Like a windows network there will need to be ongoing maintenance. Even with the growth of Linux good admins are still far and few between.
I am willing to give a rough estimate if you are thinking about the move. Just need a list of software and webpages that your office used on a regular basis. Let me know shon@shonlinux.work
