SAN user acceptance test

This is an extract from a question on SAN migration testing

In migration, you should consider several elements to form the questions you will use in the acceptance test. First you need to decide if the migration will be done while data is active or not. If you're planning to migrate while the data is not active, then you need to consider:

    After the migration, compare the data to be sure it transferred accurately.
    Are there pacing controls such that the migration can have less resources dedicated to it so more important jobs can finish?
    Can the migration be interrupted and then resumed without starting over?
    What configuration changes are required? Can the transition to the migrated device be done seamlessly?
