Our Pardot instance has recently upgraded to Advanced edition and we are planning to setup Pardot Sandbox. At present, our Salesforce Sandbox is connected to Pardot Training Environment (TE) which is replica of Pardot global/production instance. We want to maintain Pardot TE with existing Salesforce Sandbox. We will create another full copy Salesforce Sandbox to connect with Pardot Sandbox.

My question - Can we maintain Pardot Training environment and Pardot Sandbox both with two different Salesforce Sandbox? Looking forward your comments/suggestions
