How Re-Create, Copy, or Re-Use Existing WLS Domains from 32-bit to 64-bit Architecture (Doc ID 1312755.1)

Last updated on AUGUST 16, 2023

Applies to:

Oracle WebLogic Server - Version 10.3 to 10.3.6
Information in this document applies to any platform.


The main goal for this article is to illustrate the steps to migrate domains created with Oracle WebLogic Server 32-bit to a new home installed in Oracle WebLogic Server 64-bit to take advantage of the 64-bit JDK and native libraries.

If your goal is not upgrading, but changing from Java SUN JDK to Oracle JRockit JDK , you can check <Note 1058804.1> - How To Change Type of JDK (Sun / JRockit) for FMW 11g Domain.

Disclaimer note: Oracle WebLogic Server can be used as an individual product, or as the core for many other layered products, for example in Oracle Fusion Middleware 11g installations.

The objective of this article is to describe how to move "plain" Weblogic Server domains from 32- to 64-bit, and hence is not applicable to Oracle Fusion Middleware 11g product installations such as SOA, Identity Management or Portal/Forms/Reports/Discoverer.

This article is not considering whether or not the new JDK will be certified or not. Hence it is the user responsibility to check the WebLogic Server version certification matrix to confirm that your installation type supports the desired version of the JDK.

1) For Weblogic 10.3.X, check the certifications for Oracle Weblogic product in the following <Note 431578.1> - How to Find Certification Details for Oracle Application Server 10g and Oracle Fusion Middleware 11g

2) For individual Oracle Weblogic Server configurations involving versions prior than 10.3.0, check the certifications here


These steps assume that you are using origin and target installations as follows:
