What is the proper way to go from python26 to python27?

[Rodolfo Aramayo]

People,

I was wandering if there is a proper way to jump from using python26
to python27?
Is this just a matter of activating python27 using python_select?
Would the active python26 ports remain active under python27? <==I
assume so...but as more and more ports get ported to python27 would I
have to installed them in pythin27 one by one? or do I have to
re-install all my python ports again?

Thanks
