Hi,
If I set up a collaboration between this 2 portals (10.8.1 and 10.9.1), either could be the host? or should be the the portal with higher version?
Thank you.
Based on the documentation I believe either as the host should suffice, however there might be specific items or apps that are not backwards compatible, in which case the 10.8.1 Portal should host.
Hope that helps,
David
