WebSphere Application Server - Upgrade from v6.0 to v6.1

I have a custom application written using J2SE 1.4 and running on WebSphere v6.0. My application server is Red Hat Linux v5.4. Here is my issue. I need to make changes to my custom application. The IDE I'm using is MyEclipseBlue v10.7, and I'm having an issue stepping through the EJBs. I keep getting errors saying it doesn't recognize the line numbers, even though they should be there. The MyEclipseBlue Tech support is recommending that I upgrade the application to WebSphere v6.1 But if I do that, it won't run on my production server, which is WebSphere v6.0 Right? (Question 1) So I'm wondering how hard it is to upgrade WebSphere. (Question 2) I can get around in Linux but it's challenging. And my knowledge of WebSphere is just what I've picked up within the last few years. Not sure if I should go there or just keep struggling with my IDE. Any advice?
                                    Thanks!

Websphere 6 to 6.1 upgrade is not too risky if  you follow the roadmap.

Never a bad idea to to a test upgrade first.  Clone your production environment, perform the upgrade, test, and verify that it resolves your debugging issues.

IBM documents the upgrade process pretty clearly.  Follow the instructions, do a test upgrade first, make sure you have a good backup and test plan before you start the production upgrade, and you'll be fine.

If, after reviewing the upgrade instructions, you determine it is outside your comfort level, get an experienced Websphere consultant to come in and guide you through the process.

Thanks, Gary! I don't think I'm ready to go there now, but I will definitely keep your advice for future reference.

Understand.  Upgrading a single server isn't a massive project, but it is always nice to have some help the first time, just to be safe.
