I want to upgrade only our domino directory to R6, not yet the server. I put the R6 pubnames.ntf on the 5.0.5 server as told in the redbook. Then I get "Invalid NSF Function". Is there a way to keep on running my R5 server and using the design task to refresh design with the R6 pubnames.ntf? Can I revert the ODS of this ntf-file?
