Metadata components that needs to be manually deployed in Salesforce
When you want to deploy changes from one Salesforce org to another, you can choose any of the following tools to transport changes from one Salesforce org to another Salesforce org.
1. Change Sets
2.
Force.comMigration Tool (ANT based)
3.
Force.comIDE
4. 3rd Party AppExchange Product (e.g. Dreamfactory)
However, the point to note here is that not all configurations are available through metadata API. For example the following configuration components cannot be deployed using any of the tools mentioned above. These configuration components must be created manually in the target org.
