Changing the 2012R2 RDS database location from sql 2008 to sql 2014

Hello,

I need to move my RDS database and point my three RDS 2012R2 servers to the relocated db. Can this be done while users are connected or does it require all three RDS servers to be idle?

PS C:\> Set-RDDatabaseConnectionString -ConnectionBroker "rds.contoso" -DatabaseConnectionString "DRIVER=SQL Server Native Client 11.0;SERVER=newsql.contoso.com;Trusted_Connection=Yes;APP=Remote Desktop Services Connection Broker;Database=RDS"
