Example 1: Remove an availabity group
PS C:\> Remove-SqlAvailabilityGroup -Path "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups\MainAG"
This command removes the availability group named MainAG. You can run this command on any server instance that hosts an availability replica for the availability group.
Example 2: Remove all availability groups
PS C:\> Get-ChildItem "SQLSERVER:\Sql\Server\InstanceName\AvailabilityGroups" | Remove-SqlAvailabilityGroup
