General

Make sure your appinfo/info.xml allows for Nextcloud 24.

<dependencies>
  <nextcloud min-version="21" max-version="24" />
</dependencies>

Nextcloud 24 is the first major Nextcloud release to work with PHP8.1. Follow the steps below to make your app compatible.

If appinfo/info.xml has a dependency specification for PHP, increase the max-version to 8.1.

<dependencies>
  <php min-version="7.3" max-version="8.1" />
  <nextcloud min-version="21" max-version="24" />
</dependencies>

If your app has a composer.json and the file contains the PHP restrictions from info.xml, adjust it as well.

{
  "require": {
    "php": ">=7.3 <=8.1"
  }
}

If you have continuous integration set up, extend your test matrix with PHP8.1 tests and linters.
