As many of you know, Opalis Integration Server 6.3 is the last in a long line of OIS releases. At the end of this year (2011), it will be replaced by one of the System Center 2012 releases: System Center Orchestrator.

You can see the official System Center Nexus announcement here: http://blogs.technet.com/b/systemcenter/archive/2011/03/24/welcome-to-the-family-system-center-orchestrator.aspx

Along with the new name, you can also look forward to a few new features (listed and explained at the above link); and while OIS is being replaced by System Center Orchestrator, the current primary functionality (policy authoring experience) will remain the same.

enJOY!
