Migration of Java Application from WebLogic 8.1 to Weblogic 10.3

[Ikram Shahzad]

Hi All,

We got a requirement where we need upgrade an application as follows

Technology Existing version To be converted
Java 1.4.2 to 1.6
Web logic 8.1 SP3 to 10.3
EJB 2.1 to 3.0

WebLogic 10.3 supports EJB3.0 Spec. But i read elsewhere the EJB3.0 is backward compatible with EJB2.0 and EJB1.0
Is this right?

Please share your thoughts regarding this.

Yes. You can continue to use EJB 3 style beans. However, you probably want to upgrade them at some point for new development.

Hi ,

We have got a requirement of Migrating our source code from Weblogic 8.1 SP3 to Weblogic 10.3.1 Enterprise Edition server.
Can some one please provide me inputs or pointers regarding this.
I was going through some articles , in some places it was mentioned that it is a two step process, first we need to migrate the code from Weblogic 8.1 sp3 to Weblogic 8.1 Sp (4 or 5 or 6) . Then we can migrate the code from Weblogic (4 or 5 or 6 ) to Weblogic 10.3.1 using the code migration tool provided by the Weblogic 10.3.1 workshop.

Can some one tell me is this teh correct path which we need to follow for migrating the code?

Any input is welcome on this.

Thanks in advance.
