I have installed 3.1dev version instead of stable

Hello, I installed new server based on this tutorial

Code:

https://www.howtoforge.com/tutorial/perfect-server-ubuntu-18.04-with-apache-php-myqsl-pureftpd-bind-postfix-doveot-and-ispconfig/

And I have installed version 3.1dev instead of 3.1.12 stable ... can I "upgrade" my installation to stable version?

Thank you!

 

Sure. Though dev version should work fine too.
