LDN - Luminis Developer Network

We are looking to upgrade to Bb 9 on a new server and run our current Bb 6.2.3 system at the same time.  This will allow faculty to experiment with the new version and start migrating content without having to shut down 6.2.3 system.

Is there a way to have 2 SSO links for Blackboard in the Luminis portal?  Has anyone experimented with this?  We would appreciate any help on insight to this.

Thanks.
