Change sets

Explain about change sets?



A change set is a means by which one organization can send customizations to another organization. Change sets



can only contain modifications you can make through the Setup menu; therefore, you can't use a change set to



upload a list of contact records. In other words, change sets contain metadata, not data.



When you want to send customizations from your current organization to another organization, you create an



outbound change set. Once you send the change set, the receiving organization sees it as an inbound change set



Sending a change set between two organizations requires a deployment connection. Change sets can only be sent



between organizations that are affiliated with a production organization



These components we can deploy through Change Sets.

Outbound Change Sets: An outbound change set is a change set created in the organization you are logged into



and that you want to send to another organization. Typically, an outbound change set is used for customizations



created and tested in a sandbox and then sent to a production organization.



inbound Change Sets: An inbound change set is a change set that has been sent from another organization to the



organization you are logged into. A change sent must be deployed for the changes to take effect. You can deploy the



contents of an inbound change set as a whole, but not on a component-by-component basis.
