I installed all the services of SQL server 2012 (database engine, ssis, ssas, ssrs) on a sandbox with another existing version sql 2008 (db engine, ssis, ...)
The 2012 instances are named instances, and 2008 are default instances.
I read from this article: http://technet.microsoft.com/en-us/library/ms143731.aspx
it says after the second heading: You can install SQL Server 2012 Integration Services (SSIS) side-by-side with an existing instance of SQL Server 2005 Integration Services (SSIS) and SQL Server 2008 Integration Services (SSIS).
But in the table below: it says: You can only install one instance of the Integration Services service on a computer
This is confusing,
And when I connect to SSIS using SSMS, if default computer name, I connected to SSIS 10.50 which is 2008 version, there I cannot see the integration service catalog folder, but if I connet to the .\instance name, it will say doesn't support multi instances
