Upgrading from 6.1 to 9

In my experience, the key issue in migration has been the database. The database drivers that ship with Coldfusion MX6.1 are too old for Coldfusion 9. Fortunately, SQL hasn't changed that much. So, you should expect few changes in your query code. However, you have to pay attention to changes in the settings and configuration in Coldfusion's connection to the database.

See where you could improve your code using the new tags, attributes, and values since version Coldfusion MX6.1. the You should also be aware of the deprecated tags, attributes, and values and any functionality that has been made obsolete.
