The following is an overview of the procedures required to complete the ACS routine testing phase. Apply this process to each new data subtype until all data has been migrated. For the specific procedure, see Testing procedures.

• After a sample of the data sets that are to be tested has been chosen (or created), a base line test set is generated, to represent the ACS routines before they are changed.
• After the base line test set has been created, the ACS routines are changed (but not activated) to manage the data type. The same set of test cases is then run through ACS testing, generating a new ACS listing.
• A comparison test is run against the base line test set, and the new listing and exceptions are reported in a comparison report. If the change to the ACS routines was made correctly, the exceptions reported should contain only the new test cases.
• If no errors occur after converting the data to SMS management, the test cases are updated to reflect the expected results for future regression testing.
• The current configuration is saved and the new configuration is activated. After the activation, conversion of data to SMS management can proceed.
