This article is intended to answer the question as to what are the Dell EMC supported tools that can be used to migrate data between arrays.
Dell EMC recommends using EMCOPY to migrate data to/from CIFS storage. EMCOPY lets you copy a file or directory (and included subdirectories) from and to an NTFS partition, keeping security the same on the copy as on the original. EMCOPY allows you to backup the file and directory security ACLs, owner information, and audit information from a source directory to a destination directory without copying the file data. EMCOPY, however, does not copy the local groups database from one computer to another. You must use LGDUP first to copy the local groups database. Therefore, when the /lg or /lu option is specified, EMCOPY initially verifies that all of the source server s local groups exist on the target server. Even if one group is missing, EMCOPY stops and notifies you to use LGDUP first.
EMCOPY duplicates a directory tree from one server to another, keeping the security intact, including access control lists (ACLs) with local groups' access control entries (ACEs). When copying the local group security entries, EMCOPY first ensures that the local group database has been replicated on the target server. If not, EMCOPY suggests using LGDUP first. For a list of available options to specify exactly which security properties to replicate during the copy process see: Table 6 on page 26 of the Using EMC Utilities for the CIFS Environment document https://support.emc.com/docu48451_Using-EMC-Utilities-for-the-CIFS-Environment-8.1.pdf?language=en_US. A successful and complete EMCopy migration of all NT folders and files must have the Ownership and Permission attributes set accordingly:
Note: It is advised to use the UNC path to the shares, and not the IP.
Note: While EMCOPY is the EMC recommended utility to migrate data, Microsoft offers a similar tool: Robocopy
The requirements and limitations for EMCOPY are as follows:
Note: VNX does not support Encryption (EFS).
