How to deploy process(jbpm6) from old server to new server(jbpm-console)?

[bxf12315]

Hi

In my opinion, process related files: .niogit; .index; repository .

I want to copy those three files into new jbpm server .

But , i find some process(deployed in old server) , do not deployed in new server.

So, i want to know how to deploy proecess using copy files?

PS: What is the role of (.index).

Thanks
