How long to learn jazz piano?

I want to take up jazz piano. I have been playing the guitar pretty seriously for 12 years and I am an OK jazz guitarist. I also played piano for 4-5 years when I was a kid and sporadically through the years, but never serious. How long would it take me to get the technical part down for jazz piano? My ear is OK as I transcribe jazz pianists all the time?|||It depends on how advanced you are with piano overall, like whether you are very familiar with scales, chords, arpeggios etc. already. Some things different from piano solos and guitar solos is that some jazz pianists will accompany their own solos and technique on piano is more straightforward; their aren't many piano techniques like sweep picking, hammer ons/pull offs, etc. Piano is mostly about having second nature knowledge of where your notes are and controlling your sound.
