When you get full download access to the Old account, download all of the tax files to your home computer as PDF files, then again as the .taxyyy datafiles. Then back them up off computer on a flash drive. That will be your primary access to those old files. IF you don't do that, you'll have to call Customer Support every year, and show them that you paid for that year's software in your current account, before they will unlock that old account. That could be a pain. IF you have them all on you home computer (AND the backup), you'll have immediate access.
