Upgrading Your WebLogic Server
Configuration: Main Steps
Take the following steps to upgrade from WebLogic Server 4.5 or 5.1 to WebLogic
Server 7.0:
1. Make a back-up copy of your 4.5 or 5.1 domain before you begin the upgrade
procedure. After you start the server using WebLogic Server 7.0 classes, you will
be unable to downgrade to a previous version.
2. Install WebLogic Server 7.0. See the Installation Guide.
Prior to WebLogic Server 6.0, a separate download was required if you wanted
to get 128-bit encryption instead of 56-bit encryption. WebLogic Server 7.0 has
a single download for both 56-bit encryption and 128-bit encryption. For details
of how to enable 128-bit encryption see Enabling 128-Bit Encryption in the
Installation Guide.
Note: Installing the new version in the exact location of the old version is
explicitly prohibited by the installer.
