Exporting my work in Manufacturing App

Hi,

I am building an application up on manufacturing app by adding extra tails and have also done some configuring changes.

Now i want to transfer this development on another instance, how do i export the complete Application?

- I tried export option in Manufacturing and imported in another instance, didn't work. 

- I wanted to export the Manufacturing App project from the composer, but was suggested that it won't work.

- Instead i was told to export tag wise in the composer to cover all the entities of my project.

       1)  I maintained same tag name to all my extra development, which can be exported.

       2) And for Manufacturing App ,there is a common tag name using which i can export. 

                     I am not able to determine this common tag, there are tags with various vocabulary  names. 

How do i export my project (with Manufacturing App) from one instance and import it to another instance keeping all the configurations and data? 

Any suggestions?
