What is the Change Set in Salesforce?

Hello Madhulika

Change Set helps in migrating and customising data from one Salesforce org to another.

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 change set. Change sets can only contain modifications you can make through the Setup menu. For example, you can’t use a change set to upload a list of contact records. Change sets contain information about the org. They don’t contain data, such as records.

Change sets make deploying changes easier.

• Change sets represent sets of customizations in your org (or metadata components) that you can deploy to a connected org. Use change sets as a point-and-click tool to migrate your customizations.
• There’s no need to download files to a local file system. Other deployment methods require you to work with local files.
• The change set tool helps you discover and include dependent components. For example, a new custom field can’t be migrated if the custom object it belongs to doesn’t exist in the target org.
• You define the set of components once. You can reuse the same set of components for another deployment by cloning the change set. Cloning change sets is helpful during the iterative phases of a project.

Deploying with change sets involves the following steps:

• Authorize deployment connections.
• Create outbound change set in sandbox.
• Upload from sandbox to production.
• Review inbound change and deploy!

Thanks.
