Convert pickle (pkl) model to newer sklearn version

[dmoshayof]

Hi,
I have few pkl files which saved models on version 0.21.3 and those are in use now.
I want to upgrade to >=v0.22 and save the same models.
Is there a BKM how to convert those models to work with new version?
(now my issue is with Imputer deprecate but I'm not sure that's the only problem).
Thanks,
Daniel

We have these docs https://scikit-learn.org/stable/modules/model_persistence.html#model-persistence but in general, cross-version pickled models aren't supported.
