Upgrading Your WebLogic Server
Configuration: Main Steps
Take the following steps to upgrade from WebLogic Server 6.x to WebLogic Server
7.0:
1. Make a backup copy of your 6.x domain before you begin the upgrade procedure.
After you start the server using WebLogic Server 7.0 classes, you cannot
downgrade to 6.x.
2. Install WebLogic Server 7.0. See the the Installation Guide.
Note: The installer will prevent you from installing the new version directly over
the old version. You must select a new directory location.
3. Modify your 6.x startup scripts to work with WebLogic Server 7.0. See
“Modifying Startup Scripts” on page 1-3.
4. Ensure that you have considered differences in the WebLogic Server 7.0
directory structure that may require you to make file location changes before
startup. See “Understanding the WebLogic Server 7.0 Directory Structure” on
page 1-4.
5. Port your applications to WebLogic Server 7.0. See “Porting an Application from
WebLogic Server 6.x to WebLogic Server 7.0” on page 1-4.
6. If necessary, perform other upgrade procedures as described in “Upgrading
Security” on page 1-6, “Upgrading WebLogic Tuxedo Connector” on page 1-15,
and “Additional Upgrade Procedures and Information” on page 1-21.
