Project template parameters allow you to make migration settings when creating a project template. The values you specify in the project template are used as the default values by all projects based on this template provided you specify values for the parameters at the project level.
You have included the required migration solutions in the project template.
Open a project template and switch to the edit mode.
On the Project Template Parameters
tab page, you can select a use level for each interface. If you select the Project Level
checkbox, you can assign values at the project level. If you select the Execution Plan Step Level
checkbox, you can assign values at the execution plan step level.
Select each migration parameter and assign a value to the parameter in the Parameter Data
section.
Save the parameter settings of the project template.
