Prefect Community

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

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?

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

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

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)
