weblogic to websphere migration problem

currently we are using Weblogic application server and we are planning to migrate from Weblogic to WebSphere. Could anyone please let us know wha开发者_开发知识库t can be the problems occurs during this migration.

It really depends on if your applications currently use any Weblogic-specific features. If it's a custom application then you have to be familiar with the programming. More than likely, if it's a Spring-based application you will face minimal issues redeploying to a different container. If it's a 3rd party application you'll want to check the manual to see any container specific instructions.

Take this with a big grain of salt but usually going from Weblogic to WebSphere is less of a hassle than vice versa because Weblogic has less custom 'hooks' and features than WebSphere, for the most part it (Weblogic) just does a really good job of following the Java EE spec whereas WebSphere takes a ton of liberties with it.

As an example: WebSphere supports Shared Session Context between multiple applications (which is not a part of the Java EE spec) and if your apps utilize this they'll probably need some refactoring.
