I'm new in CDA (Automic).
In ARA appliaction there are:
Is it possible execute deployment workflow in Environment A (using profile1) and then autopromote execution of deployment workflow in Environment B(using profile2)?
There are couple ways you can go about it depending on your constrains.
Checkout "Package States" concept for ARA/CDA
^^^- Package state allows you to connect Workflow Executions to the event when Deployment Package state is changed. So, if as part of your application workflow, last action is to change the Package State of the Package then it can be configured to trigger automatic workflow execution with another Profile.
You can also create "Wrapper" Generic Workflow that can execute your Application Workflows with different profiles in parallel or in sequence. Actions in DM Action pack can help you with that.
CA CDA Deployment Manager Action Pack
this is possible by using the concept of package states.
You can define a package state which allows an automated promotion onto the next environment.
