Selecting Application Services to Control
Use the Application Services page to select the critical application services you want the Active Upgrade console to automatically stop and restart during the upgrade process.
If you select a service on the Application Services page, the Active Upgrade console controls the service as follows:
•When the system is split, the console saves the current Startup Type for the service, changes the Startup Type to Disabled on the Upgrade Side, and then stops the service on the Upgrade Side.
•When the system is merged, the console stops the service on the Production Side, restores the previous Startup Type for the service on the Upgrade Side, and starts the service on the Upgrade Side. This ensures continuous availability of the service, allows for comprehensive testing on the Upgrade Side, and prevents any conflicts associated with two instances of a service running at the same time.
•When an upgrade is aborted, if the system is in merge mode, the console shuts down the Upgrade Side (which automatically stops the service) and restarts the Production Side (which automatically starts the service based on its default Startup Type). This returns the system to its previous,

1.Standard operating system services do not require control during the Active Upgrade process. Select only services that pertain to your critical applications (for example, Exchange, SQL, and IIS).
2.The Active Upgrade console never changes the default Startup Type for a service on the Production Side. Maintaining the default Startup Type on the Production Side ensures that a service is always able to restart on the Production Side if the upgrade process is aborted or fails.
