The following key points will give you more information about deployment slots:

• If you have cloned the configuration of one of the deployment slots, you can edit these configurations later.
• When you swap a deployment slot with another, you will note that some of the settings will be swapped, while others won't:
  • The following are the settings that will be swapped:
    • Handler mappings
    • WebJobs content
    • App settings (unless they are stuck to a slot)
    • General settings, such as web sockets, framework version, and 32/64 bit
    • Connection strings (unless they are stuck to a slot)
    • Monitoring and diagnostic settings
  • The following are settings that won't be swapped:
    • Custom domain names
    • Scale settings
    • SSL certificates and bindings
    • Publishing endpoints
    • WebJobs scheduler
• Before swapping, make sure that the settings that haven't been swapped are properly configured in the staging slot to avoid any failures after swapping.
• When you swap slots, the traffic will be redirected to the swapped slot and no requests will be dropped. Therefore, you will notice no downtime.
