What are Chainset Deployment Sets in Salesforce?

Hello Madhulika,

I guess you meant change set. Below is the answer for the same:-

we use change sets to send customizations from one Salesforce org to another. For example, you can create and test a new object in a sandbox org, then send it to your production org using a changeset. Changesets can only contain modifications you can make through the Setup menu.

An outbound changeset is a changeset created in the Salesforce org in which you are logged in and that you want to send to another org. You typically use an outbound change set for customizations created and tested in a sandbox and that is then sent to a production org.

Thanks.
