Product:
Dynamics AX 2012
Purpose:
The purpose of this document is to explain what we can do to reuse a DIXF service of an existing AOS instance for a new AOS instance
Steps:
Copy paste the following files from the bin folder of an existing AOS instance to the bin folder of the new AOS instance:
- DMFClientConfig.xml
- DMFConfig.xml
- Microsoft.Dynamics.AX.Framework.Tools.DMF.ServiceProxy.dll.config
D365 for Finance and Operations 
Why would you copy the dll file? Shouldn’t that one be part on the installation of the DIXF, along the AOS, to bring your new AOS instance up to the same version / build?
Here we are discussing how we can utilise the same DIXF service for more than one AOS instances.
