Changing pc

Hi.  I am about to install new computers into a company and one of the staff uses TAS Books.  I want to spend as little time in their office as possible, for obvious reasons during this torrid time!

Her existing pc has Win7 and the new one will have Win10 Pro, 64bit.  She says she has an install cd, but after many years I doubt that will suffice.  Can I pre-install TAS Books here, ask her to take a back-up of her accounts and then she can restore from her backup once I have changed her machine?

Thanks
