Adding or removing secondary replicas.
Adding or removing a database.
Suspending or resuming a database.
Performing a planned manual failover (a manual failover) or a forced manual failover (a forced failover).
Creating or configuring an availability group listener.
Managing readable secondary replicas for a given availability group. This involves configuring one or more replicas to read-only access when running under the secondary role, and configuring read-only routing.
Managing backups on secondary replicas for a given availability group. This involves configuring where you prefer that backup jobs run and then scripting backup jobs to implement your backup preference. you need to script backup jobs for every database in the availability group on every instance of SQL Server that hosts an availability replica.
