Updating ten plugins at once is fast; finding the broken one afterwards is not

Situation

The WordPress admin makes it very tempting to update every plugin in one click. On a simple site that often works, but in a legacy system one incompatible plugin leaves us knowing only that something among ten changes is wrong. If a database migration also ran during the same batch, recovery becomes even harder to reason about.

Approach

I grouped plugins by function and risk. Security and infrastructure-style updates were separated from components likely to change visible behaviour. The same short smoke check ran after every group before the next one moved forward. In the Docker environment, repeating that sequence was cheap enough to keep the diagnostic boundary intact.

Outcome

The update process gained a few more steps, but localizing a failure became dramatically cheaper. We no longer needed a binary-search exercise after one large batch, and production release notes clearly showed which component group had changed.
