Catalog Manager - point release upgrade

I tried to open OBIEE 11.1.1.6.9 catalog manager using OBIEE 11.1.1.7.1 client tools, but I get following error thrown back

Unable to conned to OracleBI Presentation Server.

Looks like even though its just a point release, yet we will  have to go through upgrade assistant utility (ua.bat) in order to move to new version. Note, this is not true for RPD version. When I open the RPD version, it pops open with no issues. When saving the RPD, it gives a message that you are upgrading version of the RPD file, and once upgraded, it cannot be opened in older version of AdminTool (which makes perfect sense. Anyways it’s a good idea to work on a copy of RPD file to revert back just in case).
