Before going ahead with the Installation Process, kindly make sure of below 2 tasks:

Here, you Need to Specify your existing Domain so that it can be upgraded to 12.2.1.4 version.

That’s it.

You can validate domain-version and configuration-version by running below commands:

mohitchaudhary@MOHITs-MacBook-Air config % cat config.xml| grep "domain-version"
  <domain-version>12.2.1.4.0</domain-version>

mohitchaudhary@MOHITs-MacBook-Air config % cat config.xml| grep "configuration-version" 
  <configuration-version>12.2.1.4.0</configuration-version>
mohitchaudhary@MOHITs-MacBook-Air config %	

For Cluster Configuration, kindly run below pack and unpack commands:

On the Primary Domain:

./pack.sh -domain=/u01/app/Domain_Home/ExampleDomain -template=/u01/app/cluster.jar -template_name=weblogic -managed=true -user_name weblogic -password Welcome1

Note: You can remove user_name and password option in above command if it is giving error.

On the Secondary Domain:

./unpack.sh -domain=/u01/app/Domain_Home/ExampleDomain -template=/u01/app/cluster.jar -user_name weblogic -password Welcome1

Finally, Your existing Domain is now updated successfully and it have the latest Weblogic 12.2.1.4 version.

Now, you can restart all the services and validate your settings.

Hope it helps. Cheers!!!
