One of my AIX box is running IBM WebSphere Application Server - Express
Wondering If I can upgrade to WebSphere 51 Application Server OR do you suggest I should go for WebSphere 51 ND. And If it is possible to upgrade from Express to Application Server or ND, Do I need to deploy the application again.
If I need to move from 5.1 express to WebSphere 6.1 can I migrate from the existing version?
Thanks In Advance.
