Want to create Project based on existing project schemes (Jira 6.4.11)

[JY 김]

I use Jira 6.4.11. 

I'd like to create new project based on existing project configuration (ex. issuetypescheme, permssionscheme, field configuration scheme.. ) by REST API. 

For creating project, REST API should be provided such as 1) get schemes associated existing project, 2) create project with that configuration information. But, I can't find both of all. 

For copying or cloning project, I can't find that rest api for Jira 6.4.11.

I have already know Jira has REST for this such as "project-templates/1.0/createshared/{projectKey}". But it is available after Jira 7.0. So, I can't use it. 

What is the best solution for me? :(
