    Migrating from Weblogic 9.X to JBoss5.1

    apurva_tech

      Hello,

       

      We are planning to migrate the application from Weblogic9.1 to JBoss 5.1

      JDK version currently used is 1.5 and planning to upgrade it to 1.6 while migration .

       

      Now I want to know following things

       

      1. Architecture difference between Weblogic and JBoss Server

      2. Can we upgrade jdk1.5  to jdk1.7 directly ?

      3.As JBoss7.1 is latest version why cann't we use latest version , why use JBoss5.1 ?

      4. What are the steps/approach to be followed to migrate Weblogic9.1 to JBoss5.1

       

      I have come up with some difference between Weblogic and JBoss , please find the attachment and let me if it is right .

       

       

       

      Cheers

          jdk 1.7 is backward compatible,  that should work.

          I would suggest EAP6 which is based upon JBoss 7.1, and then you can follow this documentation

          for your migration, https://docs.jboss.org/author/display/AS72/How+do+I+migrate+my+application+from+WebLogic+to+AS+7

           

          > 4. What are the steps/approach to be followed to migrate Weblogic9.1 to JBoss5.1

          When migrating between any Java EE servers you needed to migration the application required server config

          resources, (i.e. datasources, messaging step up ... etc).  You must replace any server vendor specific APIs

          with appropriate stnd APIs or add code as needed.   Check you code for package names containing "weblogic".

          This is articulated in the above document.

           

          This is a new open source tool Windup that will help you with this.  see https://github.com/windup/windup.

            Hi Searls,

             

            Thank you  very much for you answers . I will now try to Migrate the application in the following manner

            Weblogic9.1(JDK1.5)   ---->  JBoss1.6(JDK1.7) .

            Once I migrate it to JBoss1.6 ,I can then move it to JBoss1.7 JBoss1.6 --->JBoss1.7.

            Correct me if I am wrong .

              Yes. this can be done. 

               

              Is their a  technical reason you feel you need to go to JBoss 6 and then JBoss 7?

              Why not just go to JBoss 7?
