Use the Remove-DatabaseAvailabilityGroup cmdlet to delete a database availability group (DAG). A DAG is a set of Mailbox servers that provide automatic database-level recovery from a database, server, or network failure. Before you can delete a DAG, you must first remove all servers from the DAG.
Syntax
Remove-DatabaseAvailabilityGroup -Identity
<DatabaseAvailabilityGroupIdParameter> [-Confirm
[<SwitchParameter>]] [-DomainController <Fqdn>]
[-WhatIf [<SwitchParameter>]]
