Check the new CIFS shares and make sure the users are able to read/write on the share. In virtualized environments leveraging VMware ESXi and vCenter Server, the following solutions are available: EMC RecoverPoint for VMs VMware Storage vMotion. Create an emcopy script to sync the files every night. Use lgdup.exe utility to copy local groups from the source CIFS server to the target CIFS server. You can also use the sharedup.exe utility. In many cases, when it comes to SMB data, it can be faster running the two operations vs just having one tool try to do it all. Copy the share permissions (or ACL) and the NTFS root folder ACLs from the old share to new share. Such as emcopy / robocopy maybe rsync too, that allows you to just send permissions.
Emcopy root update#
Update the DNS record too if necessary.Ĩ. It would move the data for sure, permission wise for CIFS/SMB ACLs you may need to run another tool after to just migrate permissions. This procedure entails unjoining the source and target CIFS server from Active Directory (AD), renaming NetBIOS name on the new CIFS server, joining back the CIFS server, etc. Follow EMC156835 to rename the CIFS server so that the new CIFS server will have the name of its old CIFS server. Disconnect users from the source CIFS server and make the file system read-only.Ĭ. You may also spot check the ACLs and/or run tools to compare files and directories between the source and target.Ī. I am using emcopy to copy all the shares to the SAN. Analyze emcopy log to make sure files are being copied successfully. Each DFS tree structure has a root target, which is the host server running the DFS service and. This will temendously cut the time needed to update the files on the final day of migration.Ħ. Run emcopy.exe to perform baseline copy.ĥ. Use lgdup.exe utility to copy local groups from the source CIFS server to the target CIFS server.Ĥ. You can also use the sharedup.exe utility.ģ. Copy the share permissions (or ACL) and the NTFS root folder ACLs from the old share to new share. Incremental backups should only be performed at the root volume level When backing up Unity, VNX, VNXe or Celerra systems, you should only. Maximum number of files Each individual Avamar backup of a NAS system can contain a maximum of 10 million files.

Create the necessary VDM (Virtual Data Mover), File System, and CIFS server on the target VNX machine.Ģ. When backing up a NAS system, paths cannot be longer than 4,096 characters. In general, I used the following procedure:ġ. There are several steps you need to follow for a successful migration.

One method I used recently to migrate Windows files (CIFS) was to copy files between the source CIFS server to the target VNX server using the emcopy migration suite of tools from EMC. There are several methodologies in migrating files to EMC VNX.
