MySQL 5.6 parameters

I have been performing a few MySQL upgrades from 5.5 to 5.6.   It is general a straight forward process but I wanted to discuss MySQL 5.6 parameters changes.

MySQL Upgrade and Compressed Tables

Recently one of our MySQL servers crashed.  Luckily there wasn't any damage but after a support call it was found it was due to a bug with the version we are running.  We decided to upgrade to the latest version of 5.5.  We have one physical server running 10 small to medium MySQL instances (no replications).  Whereas 9 of the upgrades went as planned one didn't (there is always one!).

I have been working on an upgrade path from 5.5. to 5.6.  The MySQL documentation is good and explains what could be a muliple phase upgrade to get to 5.5 to then upgrade to 5.6, see

Here are few notes which I hope helps.  There looks to be two ways to upgrade from 5.5 to 5.6. 
  • Import/Export
  • Binary Upgrade
