Moving Niintex workflows [Library and Reusable workflows] between TEST/QA and PROD environment.

Hi,

I am not sure if this is the appropriate forumn to post this query.

I would like to know various ways by which workflow can be moved between different environments [TEST/QA and PROD].

Is there any other way apart from Export-Import option?

Also with Export-Import option is it based on the GUID's or internal names of columns, as internal names or GUID will be different between different environments.

Regards,
