CiviCRM upgrade oddities: extension compatibility

CiviCRM upgrades should be simple, but they can include some surprises.

For example:

Are you sure that all of your installed extensions are fully compatible the upgraded CiviCRM version?

Extensions can include PHP and Smarty template file overrides, which can create surprising misbehaviors.

They can also rely on CiviCRM core code that isn't available — or that functions differently — in the newest version.

It can be hard to know ahead of time whether this will be an issue.

The solution? Make sure you're testing afterward.

Know what extensions you're using, and what you're using them for. Then after the upgrade, go back and double-check to be sure those things are behaving properly.

All the best,
A.
