Hi,

We are migrating our J2EE Applications from WAS 6.1 to WAS 7. I Would like to know if there will be any issues in it.
Is there any pre-migration steps that i should follow before i migrate to WAS 7?

Thanks in advance,
Baskaran

I have done migration from 6.1 to 7.0 without any issues. We also migrated our EJBs from 2.1 to 3.0. Removed lot of code/config/references related to EJB2.1.

Generally migrating third party framework migrations are smooth. The challenge comes when the same framework is bundled with WebSphere as well. For example: Apache Axis2 comes bundled with WebSphere, Xerces, Xalan, Commons logging etc are all bundled.

The class loader issues come up and then you have to play with class loading setting at either library level (in Axis2) or WAR or EAR level.
 
I agree. Here's the link: http://aspose.com/file-tools
