PQC: How to get ready?

What tasks we face, heading to Post Quantum Cryptography?

Anything we can do?
Having it for it self - security, see Harvest Now, Decrypt Later (HNDL) - or as a part of the learning journey.

Anything we can’t do and why?

I am currently seeking ideas, having eg. FreeIPA, Private CA and a bunch of services and hosts in place.

My base level pain is, to not have a cheap 2FA token featuring PQC mechanism, and bunch of IoT hardware which don’t have Hardware support implementation of the major PQC cryptos.
