SSIS and second SQL Server (named) instance

Hello. I have a SQL 2014 instance running Integration Services (SSIS). Subsequently I added a second SQL Instance on the same server. I can use Management Studio to connect to "Integration Services" but the content includes items (ie Maintenance Plans) only from the initial instance. How can I "add" the second SQL instance to SSIS? Thanks! :-)

Since they are separate instances you have to deploy your SSIS packages to the new instance or you need to execute the SSIS packages using dtexec and alter your packages to connect to the separate instances.

Hello Brian and thanks for the prompt reply. It completely flew by me so please bear with me. :-)

Maintenance Plans are supposed to automatically pop up in Integration Services > Stored Packages > MSDB > Maintenance Plans. In my case I only have items from the first instance. How can I fix that? Am I supposed to have a second "MSDB" subtree for the second instance?

In addition I have exported Maintenance Plans that i would like to import into the second instance. In theory I do this by going to the location above but of course the latter doesn't exist.

Notice that the new instance doesn't have an SSISDB (only the old instance does). Do I need one?
Brian CroweDatabase AdministratorCommented:
Yes, each instance has its own MSDB database and yes you will want to create an SSISDB on the new instance.  The fact that these two instances are on the same machine is really of no relevance in this case and you need to treat them as you would if they were on separate machines.

As an aside you should be aware of the extra management concerns when running multiple instances on the same machine.  I don't know if you're phasing out an old instance with an upgraded one or what your reasoning is but you will want to watch memory usage fairly closely.  You will want to make sure you configure the max memory setting on each instance so that they leave room for the OS and a little bit of free memory.

Yes I am phasing out the old instance and moving all DBs to the new one. Trying to figure out how to transfer the Maintenance Plans and SSIS packages. In this case, should I copy SSISDB from the old instance to the new?

Here is an MSDN article on how to backup, restore, and move the SSISDB.  Another option depending on how many different projects you are talking about is to just redeploy them to the new instance from Data Tools assuming that is how they were developed.
