Explanation

Data migration does not appear on the standard list of three triggers for maintenance testing. The "migration" trigger refers specifically to migrating a system to a new platform or operational environment - not the act of moving data between systems. Since data migration doesn't change the software itself or its runtime environment in the way that system migration does, it falls outside the defined trigger set.

Why the distractors are wrong (i.e., they ARE triggers):

• B. System retirement - decommissioning a system triggers maintenance testing to verify data preservation, archival, and safe shutdown procedures.
• C. System modification - any planned enhancement, bug fix, or emergency change to a live system triggers regression and impact testing.
• D. Introduction of a test management tool - this constitutes a change to the operational environment, which falls under the "modification" trigger category.

Memory tip: Use the acronym MR² - Modification, Migration (platform), Retirement. If a scenario doesn't clearly map to one of these three, it's not a trigger. "Data migration" sounds similar to "migration" but refers to moving records, not relocating a system - a classic exam trap.
