About Upgrade on CentOS 6.5 (x86_64) from version 14.12 to version 15.03

15.03 doesn't support upgrade from previous version.

If you want to save data of previous version, you get DB backup by the following way, and import to DB in different name. Otherwise, don't import and keep it intact.

How to get backup

$ mysqldump -u [User name of MySQL root user] -p [Password of MySQL root user] [Old DB name] > hatohol.sql

How to import a backup to DB in the different name

$ mysql -u [User name of MySQL root user] -p [Password of MySQL root user] [New DB name] < hatohol.sql
