We have a single server inside the firewall used for all of our production apps. The server and clients are 8.5.3.
We have a single 'portal' server outside the firewall used by a small set of our customers for read-only access to a few apps via a browser. This server is currently at 8.5.3. Mail isn't implemented on this server; customers log in, see dbs, view docs, and leave. The only admin tasks I perform on this server are to add new users and push new replicas onto the external box (which I do from my Notes client, not the admin client)
Because of POODLE, we're going to be upgrading our portal server to 9.0.1. We have no plan to upgrade our internal server (or clients).
I'm the developer and admin for both servers.
I don't intend to install the 9.0.x designer client on my system.
Do I need to install the 9.0.x admin client or can I just keep using my 8.5.3 version?
Any risks with either scenario?
Thanks for any tips or suggestions.
Mixed versions of domino server and clients can be used and actually have been used for a long time. Certainly only the intersection set of features of these versions can be used.
