Planning that new WebSphere Process Server v6.0 GA production deployment? I suggest you check out the End Of Service Dates published by IBM for your versions to ensure that you aren’t painting yourself into a corner before you even start. Beware clicking that last link, it’s a poorly created web page with every single IBM product and revision; the worlds longest HTML ever.
End of Marketing: IBM stops actively selling it to customers
End of Support: IBM stops answering the phone when you call to complain about it. Of course, you can always enter into an extended contract to continue support of mission critical installations.
I tried to get other quick links but it was too frustrating with all the product versions inlined together.
