Task 13: Upgrade Your Production Environment

The procedure for updating the Production environment must contain the same steps as your procedure for updating the QA environment. Some specific parameter values, such as host names and connection information, can be different.

If there is any significant difference between the procedure for upgrading the QA environment and the procedure for upgrading the Production environment, then document the specific reasons for this variance. For example, it might not be feasible to simulate certain aspects of the Production environment in the QA environment. By documenting this variance, you allow the people involved in your Upgrade Project to make an informed judgment as to the risk posed by this variance.
