Upgrade MariaDB from 10.1 to 10.3

Hi there.
Is it straight forward to upgrade MariaDB from 10.1 which I currenty have, to 10.3 (which is the latest version on Software Collections).

Can somebody point me in the right place to do so?


Which operating system are you on?


Centos 7 :+1:. Should have said in op.

As per another topic I raised this morning, my hand was forced.

I removed mariadb101 and then installed maria103, i’ve got it working and had to restore db backups, as they all disappeared.

For future info, when i upgrade to a new maria db version, is there a way of doing it where the existing databases are kept?

I use yum remove rh-mariadb101*

And then yum install rh-mariadb103

Thanks in advance,


This tutorial works flawlessly for me on CentOS 7: https://mariadb.com/kb/en/upgrading-from-mariadb-103-to-mariadb-104/

It’s pretty much the same process for upgrading any version of MariaDB.

Thanks for the reply.

I think the only thing I didn’t do was run the upgrade.

Would that have stopped my dbs from displaying once I started the service?
