We are considering to upgrade to MySQL 5.6 this summer. I would like to know if our data will be changed in any way once we perform the upgrade?
I've been reading and I found that mysql_upgrade upgrades the system tables only. I tested it and it seems to be true. But I just want to make sure that our data will remain the same after the upgrade. I don't want to have problems with our apps after we do the upgrade. Thanks!
