Im reciving error when upgrading, "Upgrading from GCFv1 to GCFv2 is not yet supported. Please delete your old function or wait for this feature to be ready." So current V1 function can not directly upgrade to V2?

Not at the moment. Are you trying to deploy a new HTTP/callable/task queue function or an event handling function?

[@jeffhuleatt]

Hi Ruiqi, great catch! Just like when changing a function's region, you'll need to deploy a new function name and migrate traffic to it. We've added a section to the migration guide to cover that: firebase.google.com/docs/functions/2nd-gen-upgrade#migrate_traffic_to_the_new_2nd_gen_functions

Followed this step by step still not getting option to use Python cloud functions no matter what I do, even from a new project. Of course documentation is sparse :(

probably you need to update your firebase-tools npm package
