Create Software Stacks from Existing Environments
You can create software stacks from existing installations. To do so, you will identify installations to Command Central, and Command Central will create one stack for each set of installations that are the same release, are installed on the same operating system and in a directory of the same name, and whose Platform Manager uses the same port and protocol (HTTP or HTTPS).
To watch a video that provides a step-by-step demonstration on how to create stacks from existing environments in Command Central, click

1. Go to Environments, click the environment that contains the installations from which to create stacks, click 
at the bottom right of the Environments pane, and then click Auto-create stacks. 2. In the Auto-create stacks dialog box, in the Product releases drop down, click the release of the installations from which to create stacks or click ALL.
By default, Command Central will name the stacks 1, 2, 3, and so on. In the Stack prefix field, specify a prefix for those names that will help you better identify the stacks later.
3. Click OK to create the stacks.
4. If you need a database layer in a stack, add it manually.
