Crypto agility means being able to replace cryptographic algorithms without rebuilding everything from scratch. That matters before QDay because systems that are hard-coded around old assumptions will be harder to migrate when post quantum standards become normal. For small sites, the lesson is simple: keep software current, avoid custom crypto, know where certificates and keys are used, and make future upgrades boring instead of heroic.
Opinions are my own. Obviously.

Crypto agility is not a flashy phrase, but it is exactly what will separate easy migrations from painful ones.

Avoiding custom crypto should be printed on every developer's wall.

The boring upgrade path is the goal. Heroic last-minute migrations usually mean someone ignored the problem for years.

This fits qday.forum well because it connects quantum risk with normal admin discipline.
