WebSphere and tools


We are looking at upgrading our WebSphere (current version 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 ( 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, but not WebSphere Oracle development indicated it may work, but if issues are found, Oracle is not going to patch, which makes sense. We are wondering if anyone has implemented WebSphere with tools and have it working. Did you come across many issues when testing E1 after implementing fix pack 9?
