I am new to this forum.
I am looking to upgrade a system from xp to windows 7. Its actually for a friend of mine who has a newsagents business. The tills that operate on the shop floor run software called reposs which is a point of sale software. This runs off the upstairs PC which is currently running windows xp. However i am looking to upgrade to windows 7. The issue is that the main pc located upstairs cannot be shut down as this will crash the downstairs tills/systems, basically upstairs pc is acting as a server. Any advice on how to get around this?
Would waiting until the shop closes and then completing the switch be an option or will this still crash the tills?
I know i will have to backup all the data onto an external hard disk as well. Just need help with the acting server upstairs situation.
