Volumes Error for SERVERNAME: There is no such command

We were migrating an EX server version 4.81.1147 to another server with the same version of EX using this technote:

https://solutions.emc.com/emcsolutionview.asp?id=esg71916

after copying over all of the .emx files to the new container directory, I noticed that none of the .emx files were indexed ... and when I open EX admin I got the error:  "Volumes Error for SERVERNAME: There is no such command"

Has anyone seen this before ? EX seems to be working and archiving new emails from the journaling mailbox, but the emx files that were copied over were just put into a folder and havent moved.

Any ideas ? Suggestions ? I appreciate any feedback.
