If I am going to upgrade from iRedMail 0.9.0 to 0.9.3, do I need to run every step in each upgrade located in the 'Release Notes and Upgrade Tutorials?'

After I get this answer and do the upgrades needed, then I can upgrade my iRedAdmin-Pro, right?  It gives me an error at the moment because of the 0.9.0 version too old.

thanks!
