@kdawes01 Have a read of this thread: Question - Is MariaDB going to be updated with Plesk updates << The Plesk article linked in that thread, also contains warnings and a link to another Plesk article (upgrade from MySQL 5.1 to MySQL 5.6/5.7) which it looks like... you may need to do first...
Evidently in my original question I should have mentioned that I'm on Centos 6.10. Can I even *have* MariaDB on Centos 6 or would I have to have Centos 7?
Is there a way to upgrade from Centos 6 to Centos 7? (Evidently Centos 7 comes with MariaDB built in)
Yes... but, within the comments on the Plesk article that is linked within that thread... user @ Stefan DOES ask the same question as you have (below) It is answered by Plesk but the answer is not currenty viewable
