You are missing a bunch I think. The arch migrations and a few others have special minimigrators attached to them.

Shouldn't the list be pretty much all migrations imported in make_migrators, i.e.:

cf-scripts/conda_forge_tick/make_migrators.py

Or was the intent perhaps to list a subset of all migrators? I think that for tracking principles it would be best to go with a full list, marking as "done" either migrators updated or not applicable.

[beckermr]

We do not need to convert all of them. Many are old or not needed any more.

[mgorny]

@isuruf, perhaps you have an opinion which of these migrators should be ported, and which left alone?

[isuruf]

Most important ones are

ArchRebuild
CrossCompilationForARMAndPower
CrossPythonMigrator
CrossRBaseMigrator
GuardTestingMigrator
UpdateCMakeArgsMigrator
UpdateConfigSubGuessMigrator
