Concurrent task execution

Some system upgrade operations require considerable time. To reduce the duration of a redundant system upgrade, you can perform some actions concurrently.

The following table lists the redundant system upgrade workflow tasks in a format that involves two operators, A and B, who perform tasks concurrently when possible.
