Upgrade PHP and MySQL versions&lt;/b&gt; is selected, when &lt;a href=&quot;/support/training/course/index.php?COURSE_ID=113&LESSON_ID=9575&quot; target=&quot;_blank&quot;&gt;background update task is in progress&lt;/a&gt;, and PHP and MySQL will be finally updated to their current version.&lt;/p&gt; &lt;p&gt;If you need to roll back from PHP 7.x to 5.6, it can be done by selecting the item &lt;b&gt;1. Rollback php to 5.6 version&lt;/b&gt;: &lt;/p&gt; &lt;p&gt;&lt;img src=&quot;/images/bitrixvm/vmbitrix7/manage_pool/vm_rollback_php56.png&quot; /&gt;&lt;/p&gt; &lt;p&gt;If you have updated &lt;b&gt;BitrixVA/BitrixEnv&lt;/b&gt; to version 7.1 and higher, then you will have an option to update MySQL version to 5.7 Percona DB. It can be done via selection of item &lt;b&gt;2.

You can check the currently executed tasks by using menu item &lt;span class=&quot;path&quot;&gt;5. Background tasks in the pool &gt; 1. View running tasks&lt;/span&gt;.
