When to run upgrade.php

It doesn’t hurt to run it multiple times. Running it whenever the upgrade*.php files change will be sufficient. Any database change should be accompanied by an update to upgrade-functions.php.

Thanks rboren!
That’s what I figured and had been doing, but just wanted to double-check.

Will an upgrade overwrite pages? (Like my slightly modified index.php?)

No, running the upgrade script only modifies the database.

ok, thank you
