Hi All

We are supposed to migrate Weblogic 8.1 to Weblogic 9.2.
I am trying to get an idea from the weblogic docs.

However, I feel that I wouldnot require all the detailed stuff that takes to have the server upgraded.

Is there any documentation available that gives an highlevel idea on what aspects have changed, so that I can brood into further details if applicable to my task.

You need to be careful there. Migration and upgrading are 2 different things. Migration is generally referred to when an application running on weblogic 8.1 is deployed on weblogic 9.2
Whereas, upgradation means you are upgrading your installation of weblogic 8.1 to weblogic 9.2.
Not sure but I do not think there is any migration guide provided by weblogic on this.
Depending on what your application is, what components it consists of you would have different steps to migrate. A good starting point is changing the jdk version used for building the code. weblogic 9.2 ships with jdk 1.5 as default.

We use basic technogies like JSPs,Servlets,JDBC and EJBs in our application.

While we upgrade to Weblogic 9.2, I would like to know key issues at a highlevel that we may face with the existing application using the aforesaid technologies post upgrade.

The BEA Weblogic site does provide some known issues with this upgradation,but they appear to cater to different arena like Webservices or Security which we donot use.

I would therefore like to know any general issues that may crop up after the upgrade on the application using the abovesaid technologies.
I agree. Here's the link:
