摘要： A method of upgrading an application in a software-defined data center (SDDC) includes: deploying, by lifecycle management software executing in the SDDC, a second appliance, a first appliance executing services of the application at a first version, the second appliance having services of the application at a second version, the services in the first appliance being active and the services in the second appliance being inactive; expanding, by the lifecycle management software, state of the first appliance to support both the services at the first version and the services at the second version; replicating, by the lifecycle management software, the state of the first appliance to the second appliance; performing, by the lifecycle management software, a switchover to stop the services of the first appliance and start the services of the second appliance; and contracting, by the lifecycle management software, state of the second appliance to remove a portion unused by the services at the second version.
