A client of mine has a computer running applications for roughly 10 machines. They need a real server to handle all of this and I'm going to make some recommendations and install/migrate everything.
Because they are running legacy apps I'm going to create a virtual hard disk of the old operating system and run it on the new server within virtualbox.
I want to make sure this process goes as smoothly as possible.
What information do I need to gather from the old computer and the new server to ensure maximum compatibility in this migration?
