cifs share migration from EMC VNX to NetApp

FelixZhou

we will need to migrate a cifs file system with multiple shares from EMC VNX to NetApp, can someone share your experience?

1).  move data from share to share or from file system to volume? which way is better?

2). is that possible to maintain all share permissions?

3). what is the best utility can we use for moving data?

thanks and have a good weekend !

Hi,

 

Your best bet is 'robocopy'. I have used robocopy once upon a time 😉 to migrate data between EMC and NetApp and it worked very well, it's been a while and have never had another opportunity as I landed in all NetApp environment since then fortuantely.

 

There are many discussions on the Internet that I am sure you would have looked up by now but 'robocopy' tops it as far as CIFS is concerend.


Few articles worth reading:

(I have used the commands shown in this article and it works well, it preserves the file/dir attributes & permission)

You may give it a try NetApp's tool:[This is an old tool and have never used personally, so can't vouch for it]

EMCOPY: I believe its a native tool for EMC and it also works, though I have never used it.

 

Example command: [Shows basic switches, you can experiemtn with 'multithreading']
robocopy \\192.168.0.x\share \\192.168.0.x\share /E /ZB /DCOPY:T /COPYALL /R:1 /W:1 /LOG:C:\robocopy.log


1) move data from share to share or from file system to volume? which way is better? = Both works

2) is that possible to maintain all share permissions? = Yes

3) what is the best utility can we use for moving data? = Robocoy

 

Try it out with few shares and make a call.


Thanks!

NetApp offer xcp for this kind of migrations. I used it to migrate 50TB from emc isilon to ontap 9.6 a work great. It also preserve ACL information.

Agreed. Robocopy is still single threaded. XCP is multithreaded and works very well for this purpose.

Bydefault, it runs single threaded but there is /MT switch there.
