I’m running Windows 7 Pro with ACA & Revit 2014, and I would like to upgrade to Windows 8.1. Are there any issues that I should be concerned about and is this worth the effort?
Can't give you real world advice since I am skipping Win 8/8.1 and won't touch the product until Microsoft truly learns its lesson about reducing productivity by removing the start menu and its powerful search function. In other words waiting for Win 9. *End MS rant*
The differences between Win 7 and Win 8.1 aren't worth the hassle IMHO. 8.1 is a faster OS on its own with proper hardware. All they really did was optimize the OS for tablet applications and change the interface, no really great 'I NEED that feature' for me. Installing Revit might be troublesome, ACA would probably do okay on 8.1. In both cases you are on your own for support.
Just my 2 cents, search the forum for others opinions, this subject isn't new!
From a "networked office" standpoint - you would need to consider all equipment at your location you'll be using. For example, if your server is compatible with Windows 8.1 connections. Is your copier/plotter have drivers for their equipment too.
It can be a big hairy mess.
