Mistral Deprecation Game Plan

[arm4b]

Mistral deprecation in favor of new workflow engine Orquesta was communicated for quite a long time.
StackStorm v3.2 will be latest version to ship Mistral with full removal in st2 v3.3 per Roadmap.

There is a helper Mistral -> Orquesta conversion tool available:

Special thanks @nmaludy an EncoreTechnologies for the tool

So, would it be a valid assumption that PostgreSQL would also be removed from v3.3?

[arm4b]

@Deepika-Kamalla That's correct.

[Deepika-Kamalla]

Thanks, Armab!! Is there any tentative timeline when v3.3 would be GA?

[arm4b]

No timeline yet. This is something yet to be figured, considering recent LinuxFoundation transition.

I'll start looking at the one-line installer changes.
