Generally with these migrations biggest problem in my experience is that all the operational learnings are not transferrable.

You often want to create expertise and achieve operational excellence with the tech that you start out.

Back in the day we used to say "you choose your database once". You can swap in/out a lot of things, but your data store is really the core.

It is shockingly hard to change your storage engine once you are serving customers, so you really want to get that right.

Exactly, languages and frameworks come and go - but get the data layer right and you’re set.
