Hi there. I am a newbie in  computer science. I have a nice Precision M4500 and recently I bought a Latitude E6420 as an emergency backup for M4500. I like m4500 pretty much. Very fast good workstation. But it is getting old (relatively) and recently  I have created full system back-up and a system repair disk. Now I would like to transfer full system, or at least installed software, from my Precision M4500 to my Latitude E6420. M4500 has I7 processor, 1 gig video card, 4 gig memory, windows7 PROFESSIONAL-32bit, The  latitude has I5 processor, 500mb video card, 4 gig memory, windows7 PROFESSIONAL-32bit. Computers are manufactured at about same year, 2012 or 2013 and purchased refurbished from Dell. Please, could some computer guru here guide me on the process and options. I pretty much interested in software. The soft is old but I got used to it and setup discs are damaged. I have read about zinstall and pcmover but may be it is possible to transfer system between similar computers without them. The problem I expecting could be Windows product key. In the battery compartment it is a label and it is different for each computer.

Sincerely, John Petrovich
