MySQL 5.1 to 5.5 Migration

Justin Bassignani

We're looking to migrate an existing Confluence 5.6 instance from CentOS6 to RHEL7. The current database is residing on MySQL 5.1, but RHEL7 only supports MySQL 5.5 or greater, which needs to be pulled from MySQL's repo. Should we be able to export/import the data across minor releases of MySQL without issue? If not, should we be able to upgrade a CentOS repo provided MySQL 5.1 instance with a standalone MySQL 5.5 RPM, as the EL6 repos only support up to MySQL 5.1? Thank you.

Hi Justin,

I was able to import the 5.1 data into a 5.5 once and it went smoothly. I do believe it's a smooth transition but I recommend to do this first into a staging instance and performing some extensive testing searching for issues before deploying on production.

Now going from 5.1 to 5.6 might be a huge step. 

I hope this help.

Cheers,

Rodrigo
