We are looking at upgrading our WebSphere (current version 220.127.116.11) to WebSphere 8.5.5 on the IBM i. This is a pre-cursor project to upgrading our iSeries o/s from 7.1 to 7.2. Our WebSphere consultants are hoping to install WebSphere V8.5.5 with fix pack 9 (18.104.22.168). We logged a call with Oracle support, and development came back and said fix pack 5 for WebSphere 8.5.5 has been tested with tools 22.214.171.124, but not WebSphere 126.96.36.199. Oracle development indicated it may work, but if issues are found, Oracle is not going to patch 188.8.131.52, which makes sense. We are wondering if anyone has implemented WebSphere 184.108.40.206 with tools 220.127.116.11 and have it working. Did you come across many issues when testing E1 after implementing fix pack 9?
