There will come a time when you need to replace a PC, hopefully on your terms rather than in the event of a PC failure. My suggestion, If the computer is on it’s way out, do not wait until it is too late otherwise you may have to start from scratch. This post is to help facilitate that migration from one PC to another. This is also a great way to back up your software, so in the case of PC failure, you have a plan B.
Please note* You will still need to add your printers and log into your sharing/email accounts.
