Before initiating a switchover, a dry run can be used to estimate how long a switchover takes. A dry run is a simulation of a switchover. A dry run can be set up to run automatically or manually triggered as needed.
An Automatic dry run occurs when:

Setting up a manual dry run is the same as creating a slot for a switchover, but it needs to be marked as a dry run and have migration paths assigned to it.
To start a dry run, take the following:
1. Go to the Current event screen in the Switchover module and click the Start new event button as shown in the following figure: (If an event is running, click Close Event.)
