## Requirements

1. The latest iRedAdmin-Pro always requires the latest iRedMail stable release,
so you __MUST__ upgrade iRedMail to the latest stable release before
upgrading iRedAdmin-Pro.

* If you run the latest iRedAdmin-Pro with old iRedMail release, you may
get error due to missing some required ldap attribute/value pairs
(OpenLDAP backend), or missing some required SQL columns.

* If you run the latest iRedMail with old iRedAdmin-Pro, you may get error
due to missing dropped SQL columns, or created accounts may miss some
properties required by the latest iRedMail.
