Within the Deploy an ArcGIS Solution task you can configure how solutions are deployed from the options menu to the right of the search bar.
|Use Existing Items in the Organization||By default if an item has already been deployed in the organization it will not be recreated when deploying a new item. If you need to create another version of a solution in your organization disable this option.|
|Use Organization's Default Basemap||By default web maps created during deployment will use the basemap configured for the solution. To use your organization's default basemap enable this option.|
|Add GPS Metadata Fields||When enabled feature layers created during the deployment will have additional fields which can be used by ArcGIS Collector to capture GPS metadata when editing point features.|
|Spatial Reference||Specify the output spatial reference of feature layers created during the deployment. By default the output spatial reference is WGS 1984 Web Mercator (Auxiliary Sphere).|
