MariaDB: I am using version 10.11.2 without any issues.

PHP: 8.0 or 8.1 is the current IPS supported versions.

Redis: Version 6 according to IPS because version 7 is not yet support by PHPRedis extension, but I am using version 7 without any issues.

Elasticsearch: At least version 7.2.0, but less than version 8.0.0.

Before update make sure you disable all third-party plugins and app, and before enabling them back to make sure you update them to the latest version where they are compatible with PHP 8 and support IPS 4.7.
