One finding.. when I started up my SQL Server 2008 R2 Developer edition SSMS, I was then able to connect to my registered Integration Services server which is also SQL Server 2008 R2.
Within SSMS --
is it true --- you can only connect to SQL 2012 Integration Services using SQL Server 2012 SSMS?
is it true --- you can only connect to SQL 2008 R2 Integration Services using SQL Server 2008 R2 SSMS?
is it true --- you can only connect to SQL 2005 Integration Services using SQL Server 2005 SSMS?
