Emcopy error: ERROR (6) : Lookup account sid from \\server failed
We are doing migration of CIFS servers without downtime & I am getting the following error during emcopy command executions:-
EMCOPY Errors :- ERROR (6) : Lookup account sid from \\server failed.
Finally I am getting failed copy files for 5! (emcopy clearly suggests unable to open file errors from source cifs). But this is not the problem (since we've not taken downtime), strangely I am noticing few folders & files which are 0bytes in size and also some of the Files/folders don't exist.
I hope this is not new to the experts here, eventhough I didn't find any related forums. Thanks in advance.

You can use /purge option as it enables the deletion of the files and directories fromt he destination tree which do not exist in the source one.
And I would suggest you to provide us the version of EMCopy you are using so that we can investigate the issue that you have reported
Thanks

I should've given these details in the beginning itself.
I am currently using Emcopy-04.14 (last week-incremental update), but I've used the Emcopy-04.10 for initial copies before this(for same cifs server migration).
Sameer, I am using purge option, below is the snippet of all options used:

On destination, many files of 0bytes size have old last-modified dates. So using /d option might ignore these files, but again I don't want to perform the full copy of the filesystem once again.
One of my colleague suggested to use emc46968, but it is already applied on the destination NAS.
