Celerra

Question

We are about to begin migrating filesystems, CIFS and NFS shared, from Celerra to a new VNX5500. Some filesystems are shared as both CIFS and NFS, the clients are running Windows, Linux and MacOS. WE are looking into tools to do the job, and have some questions we hope the forum can help us with. EMCCopy: - will EMCCopy copy UNIX permissions as well as Windows Permissions? - The Mac users can store files with characters that are 'illigal/special' characters in Windows.      How will EMCCopy handle this?      Does anyone know of any script or similar that we can run to change the names of such files before doing the copy operation? - I have read in a this forum that EMCCopy can do incremental updates.      Does it do this automatically? (I cannot see a switch for enabling this in the readme.) - Is ther any guide available with examples for EMCCopy? - I assume EMCCopy will be limited to 256 characters in the path?       How is this solved?           I assume use the /lev:N option to scan a certain depth, and then run repeated sessions from/to mount points furher down the filesystem structure. NDMPCopy: - The Mac users, again, can store files with characters that are  'illigal/special' characters in Windows.      Can NDMPCopy handle this? - The path limitation, does NDMPCopy suffer the 256 character limit as well? - NDMP over FibreChannel AUX port on the Celerra and VNX?      Is it this possible with NDMPCopy to use this connection when copying from Cellera to VNX? Regards Harald

If you have the opportunity to upgrade your old box to 5.6.47, you can use IP Replication between it and the VNX. Then, you'll be sure to copy everything, and all permissions will be identical. You can also set this up at any time before your actual cutover, and your filesystems will be exact copies up until you perform the actual cutover. This will decrease your downtime, since you'll have to be offline for the duration of the actual copy.

I'd rather use on-array tools than host-based tools any day. Removes at least one layer of abstraction from the equation.

I second this approach. Note, however, you're probably going to have to upgrade your Celerra to DART 5.6.47-11 or later to be able to use Replicator v2 to your VNX. Your EMC sales rep could get you a temporary migration license for the Celerra and VNX - this would be much easier than third-party copy.

Yes, for the purpose of upgrading from Celerra to VNX you get temporary (1 year I think) licenses for Replicator from EMC

Any yes – its by far the easiest and fastest migration method (unless you have a FMA/CTA with migration capabilities)

For the CIFS part I would suggest to move the CIFS servers into a VDM – this way you can also replicate the VDM and don’t have to manually migrate shares, localgroups, … Rainer

Cool, Replcator it is then... the CIFS servers are alredy all VDM's.Thanks!
