iRedAdmin-Pro-1.2.0 is NOT RELEASED YET, DON'T APPLY THIS.

Update iRedMail to 0.6.0

Alought iRedAdmin-Pro works with iRedMail-0.5.1, it's still recommended you to update your exist iRedMail installation to 0.6.0:

• Upgrade iRedMail from 0.5.1 to 0.6.0

Alter MySQL Database

• Update SQL database to add new table: iredadmin.updatelog. This table is used to store iRedAdmin-Pro update log, so that you don't want to check new version every time you log in as domain global admin.

$ mysql -uroot -p iredadmin
