# Previous Setups

Each patch configuration must contain at least one latest setup and one previous setup in order for you to create a patch. To add a previous setup to a latest setup, right-click on the 'Previous Setup' sub-node of a latest setup, and select 'Add New Previous Setup.'

You can have multiple previous setups per latest setup.

Every application or setup that you intend to patch to a latest setup must be added to the previous setup node.

## Example

Your company supports versions 1.0 and 1.1 of an application, and you want to upgrade both of these applications to version 2.0. To create a single patch to upgrade both versions, you would add V1.0 and V1.1 as previous setups to the latest setup. Your latest setup would contain V2.0.
