WebSphere magazine?

Hello --
We are currently in the process of migrating from WebSphere Application Server 3.54 to WebSphere Application Server 4.03. Our development environment is migrating from WebSphere Studio 3.5 and Visual Age for Java 3.5 to WebSphere Studio Application Developer (WSAD) 4.03. I am looking for a magazine with tips and tricks for both WebSphere and WSAD. I have found WebSphere Advisor at ibmadvisor.com. This is the first one that I've found. Has anyone used it? Is it helpful? Would you recommend this publication or are there other magazines available that would be more beneficial? Any input is greatly appreciated.
Thanks in advance.

Check out the following resources.
for WSAD:
1) WebSphere Studio Application Developer Migration Guide

Note: This is the same migration guide (i.e. migrate.pdf) found in \readme\en\ folder of the WSAD Windows installation CD. You should always refer to this guide for the latest migration information.
2) WebSphere Studio Application Developer Programming Guide, Part 4, Chapters 13, 14, and 15

Jay,
Thank you very much for your reply. I have read these articles previously and found them very helpful. Now I am looking for recommendations on a WebSphere periodical (magazine, newsletter, etc) that would provide general performance and development tips and tricks for WebSphere Application Server 4.0x and/or WebSphere Studio Application Developer (WSAD). Do you have a favorite to suggest?
Thanks in advance.
