It transfers programs and data from one PC to another across different Windows versions too.

I've never heard of it. My brother is asking me about it because his wife has bought a new PC.
BestBuy recommended it to them.

I told him I'd do manual installs of programs and transfer things like bookmarks and password files manually and/or from the cloud if they have them stored there and to move media files to an external drive for storage or later transfer.

It also seems kind of expensive at over 100 dollars. Googling online reviews seem mostly positive if they're all legit.
