I searched about cloning or copying weblogic and it's domain, and found 2 ways that I think is the most nearest to my question.
1, [packing and unpacking a weblogic domain](https://docs.oracle.com/cd/E23943_01/web.1111/e14144/intro.htm#WLDPU162)
2, [Creating Extension Templates](https://docs.oracle.com/cd/E28280_01/web.1111/e14139/appbuild.htm#g1075657) .  

There is weblogic 12.2.4 installed on Linux server and I want to coppy it's configuration and domain and create my own instance with exact configuration.
If it's possible, pleas give me solution or some clues and key-word to search more.
And do I need to change some configs by hand or provided tool does everything?  

Is copying domain different from copying weblogic configuration?
Thanks very much.
