Example 2: Migration of changes with set ranges

This example uses the scenario described in Example-1-Ongoing-migration-with-adjusted-ranges. However, in this example, instead of setting the range of the time frame from a point of consistency to the current time, you set the time frame from a log mark to another log mark. The log marks use a BMC AMI Log Master feature to create points of consistency (quiesce points).

Be sure to create quiesce points if you use this technique. If you create the log marks without quiesce points, you can fail to capture transactions that are in process at the beginning or end of each run.

Following table provides a high-level task list for this example.
