We have a primary BM server running as a proxy server at our HQ location. A secondary BM Proxy is running at another site. We use ZENWorks to switch users to the secondary proxy server if needed. They both share the same proxy rules from the top of the tree.

I would like to ugprade the secondary proxy server first to 3.9 and check it out over a week or so prior to upgrading the primary. Could this upgrade create problems with the primary still running 3.8?? Same NDS tree, same rules...

Both servers are running NW65SP6 and use traditional volumes for caching.
