Perry Myers (comment 1 in ): 
RHOS 3.0 users relied on the mysql 5.1 database shipped in RHEL 6.4

RHOS 4.0 users will be using mariadb 5.5 which is available as part of the Red Hat Software Collections (RHSCL)

We need to make sure that migration path from RHOS 3.0/mysql5.1 to RHOS 4.0/mariadb5.5 is well documented and stable.

This bug is to track creation of a set of scripts/HOWTO on this migration (which should be offline)

Comment 3 Summer Long 2014-07-21 00:09:30 UTC
Assigning to Andrew Dahms, as the designated author for generic database issues. Also switching to upgrade docs.

Hi Lars,

This is Andrew from the RHOS documentation team in Brisbane. Would you be able to answer a few quick questions regarding the process for upgrading from mysql to mariadb?

Namely -

1. When should the upgrade be performed - before upgrading OpenStack components, 
   or after?

2. To confirm - does the openstack-db command also upgrade mariadb, or must users
   follow the manual process?

3. Does upgrading the database by removing mysql, installing mariadb and running
   'mysql_upgrade' affect any of the data inside the database?

Any information you could provide would be greatly appreciated.

Kind regards,

What Changed
A new procedure on how to upgrade from MySQL to MariaDB was created and added to the above three articles.

This procedure is titled "Upgrade the Database Server", and can be found near the bottom of each article.

Included from Version 1 of each article.

Moving to ON_QA.
