    Has anyone upgraded Websphere from version 6.1 to version 7?  If so, how long did it take you to complete?  How easy or difficult was the upgrade?

      I would recommend just uninstalling v6.1 and reinstalling v7. The uninstaller is flawless for the WebSphere components and uninstalling/reinstalling will allow you to avoid any java issues between v5 and v6 as java6 is required for WS7 and java5 is required for WS6.1. The WS upgrade path is wonky. Redeploying the apps, etc is required either way.

        Thanks Matt. If I upgrade to java6, don't I have to upgrade Bouncy Castle as well? I believe I do, but I just wanted to confirm that.

          You can also create a separate instance of Websphere so that you have 6.1 and 7 running. This will make for a quicker switchover at go live.

          Then all you have to do is update /etc/lawson.env

          You will need to update to Java 6 and the new version of Bouncy Castle.

            Wow, that's cool. How difficult is it to do the separate instance of Websphere?

              Not hard. I didn't do the actual install, but all you have to do is install it in a separate folder structure.

              We have

              /WAS/

              and

              /WAS7/

              The only issue with this is you cannot use the same ports as you are currently using. If you want to use the same ports you will need to uninstall and reinstall.

              We have not had any problems so far with having different ports, but we are not live yet we are still testing. So far so good.

                Did you get Websphere V7.0 working? If so did you get bouncycastle working? Did you use the Sun version of the local_policy.jar and US_export_policy.jar files or did you have to use and could you find IBM Websphere versions?
