I have done little work with MySQL compared to MSSQL 2000 through 2012.  The version installed now on windows is 5.1.   Is there a pressing reason to go to 5.5?  Since the server uses Plesk, 5.5 is the highest supported.

This is probably beyond the scope of what can be said here, but just on security alone, I would upgrade.  

Here is a lot of reading that can be done: http://dev.mysql.com/doc/relnotes/mysql/5.5/en/

I would focus on Milestone 2 and General Availability.  And I would recommend testing.  

Maybe some others can give you more specifics, but I don't know them off the top of my head.  But, 5.5 has been out for a while.

I was really looking for some easy bullet points of something major.  As I have done my own research I am upgrading.  The latest and greatest plesk 11.5 has mysql 5.1 as default.  5.5 is the highest it supports as of March 2014.    

Over the next several years I am going to start migrating off windows and any type of panel.  

Thanks!

The update is plesk 11.5 can't support mysql5.5  So I am skipping this for now.

I understand. I don't know much about Plesk, but the underlying MySQL server should still be upgrade-able.  

In either case, i would run this in a test environment before doing this to production.  :-)

Hope this helps.

I am holding off using mysql because of the version.  The problem with plesk is if I install something outside of it, there can be issues down the road.  My plan is to get out from using the panel.  Because I have used it for so long, each upgrade it is just easier to move plesk and all the settings.  The next upgrade will be bitting the bullet and no panel.   I am use ms sql2012 and nothing wrong with that. I feel more comfortable sticking with ms right now than going to the lower version of mysql.    My long term goal is not going to be relying on dedicated servers but first I have a lot of legacy stuff that needs to be converted.   I am not in a hurry.
