Question

is there going to be any way to run prefect 1 0 and 2 0 in the same installation for backwards compatibility it d be nice to have a way to experiment with one or two flows without mixing environments branches

Kevin Kho · Answer

I don t think so because all the imports will change

not sure what that means say I want to change exactly one module to use prefect 2 0 if I could `pip install prefect2` and `import prefect2 as prefect` just inside that one module then everything else in the codebase could still work and I d only have to update the one file is there anything that would prevent me from doing that

Kevin Kho · Answer

I see what you mean Let me ask the team what the thought around this is

Kevin Kho · Answer

The API isn t backwards compatible so even if they could be installed side by side which would require a different package name and ensuring all the same dependencies code wouldn t trivially transfer between them The 2 0 is specifically to indicate that this represents a breaking change from 1 x

Brett Naul · Answer

yes that s exactly why I meant by gt I d only have to update the one file in particular I already have a branch that is using the 2 0 alpha for some things but every other piece of code that I didn t update can t run because of all the breaking changes if they were simply different packages then there d be no issue personally I think releasing an entirely different package under the same pypi name is not really the way to go but it seems too late for that
