Updated MySQL

I just updated three projects I am working on from MySQL 5.1 to 5.5. The updates were very smooth, I did backup my databases first and ran a test update on the smallest of the three installations to weed out any remaining issues in the my.cnf file. I also ran a ‘mysql_upgrade’ check before I updated to make sure there were not lingering issues. Once I was comfortable upgrading was a breeze.

The one thing I noticed is that MySQL seems to be a bit faster now, but maybe that is just an impression.
