Before running emcopy to migrate data in production environment, it is always recommended to execute multiple test runs to solve all authentication and permissions errors.

There are two ways to check for EMCopy error codes:

1. Using Windows MSDN link below that will reference how to read those errors:

Examples:

ERROR_SHARING_VIOLATION
32 (0x20)          The process cannot access the file because it is being used by another process.

ERROR_ACCESS_DENIED
5 (0x5)          Access is denied.

ERROR_FILE_NOT_FOUND
2 (0x2)          The system cannot find the file specified.

ERROR_NETNAME_DELETED
64 (0x40)          The specified network name is no longer available.

2. Using net helpmsg from the windows command line:

Examples:

net helpmsg 32
The process cannot access the file because it is being used by another process

net helpmsg 5
Access is denied

net helpmsg 2
The system cannot find the file specified

net helpmsg 64
The specified network name is no longer available
