I have Precision T3400 Workstation with Windows XP Pro x64 and also Vista. How do I migrate to Windows 8.1 ? To migrate do I have to format, thereby delete everything on the hard drive and start from a blank hard disk? This sounds so worrisome. Many programs are installed on the computer. I would appreciate anyone's advice on how to proceed, assuming I purchase a retail Windows 8 or 8.1 CD or I choose to download the software from Microsoft Download.
Thanks
