Thank for the reply good sir. The EPM version was endpoint 15.0.39.20. I just pulled it from the edge repo to get to endpoint 15.0.39.27 and I am still receiving the same error when trying to migrate to the new DPMA. The phone config file location is located in the /tftpboot dir of the system. Is that what you are referring to?
I was able to resolve the problem by removing the endpoint (dependencies) and reinstalling all apps. The problem, which I am still working through it the configs were removed which I just need to re-add. Thankfully there were only three of them that have to be rebuilt or re-added.
