Dynamics CRM 4.0-2011 Upgrade Tip #5: Remove unsupported database changes

As you used your Dynamics CRM 4.0 database you may have had occasion to add "unsupported" objects to the database.  These could be anything from indexes ( fairly supported ) to triggers ( pretty unsupported ) to custom stored procedures.

You need to consider removing all of these additions prior to the upgrade.

The pre-upgrade validation checks will give you a warning that unsupported things exist and the installation may actually fail, depending on the changes you made.  And as noted by an article, item #3,  from Customer Effective, the error message may not be very clear as to what the problem is.

Just a word of warning.
