switching from pc to mac

Hello all,

I'm looking at switching to a macbook pro - I currently use a windows laptop. Can I transfer my adobe photoshop and lightroom packages from a pc to a macbook pro? Would there be any problems with this in terms of licensing or can I simple close my phothop and lightroom on my old windows pc and just load them up again on my new macbook?

I'm not very tech savvy so these kind of things confuse me.

Thanks
