Any known issues with Notes Client 4.5.x connecting and working on Domino 6.5 ? Who´s operating such an environment?

Has anyone gained experience with Notes Clients 4.5.x connecting to a Domino Server 6.5 ? We plan to migrate our servers from 5.0.11 to 6.5 but we have lots of 4.5 Clients (on OS/2 !!) in our environment.

The mail-design will remain on R4-template.

I heard that C&S causes problems ??? That´d be bad, cause we use C&S a lot. I think I have to try it out but maybe there is someone who can give my some hints.

Thanks for any replies !

Sincerely

Bastian
