CIFS Migration from AFF400 to AFF400

[Prab]

Hi Folks,

I need to do the migration of CIFS shares from AFF to another AFF. I thought of using the snapmirror and transfer all the data between netapp's and finally make the destination volumes as RW and mount on the junction path with same names as source netapp. Below are the questions that i have.

1. Is there any other better way that i can use for this migration?

2. If i do the above method will the permissions for CIFS share are also copied to the destination netapp after i do the cutover with snapmirror? ( When i do the snapmirror the volumes are RO and after the cutover i get opportunity to verify the permissions so is there any other way beforehands i can checks the permissions on the newly created share in destination array.) 

If anyone who has done can please share the experience and issue if any with the above approach?

Upgrade to 9.10.1 (latest P release) and use SVM migration - https://docs.netapp.com/us-en/ontap/svm-migrate/index.html

alternatively, if an upgrade is not available at this time, SVM-DR with identity preserve true may be a good option as well.

Hey @AlexDawson -- This is between the different datacenters and IP's will be different and as per the prerequisite it should be in same network which will not work for me. They will be in same domain but ip's will be different.

Both the options suggested by Alex & aladd are the best alternative methods to get the job done without much manual interventions.

However, if you just want to use "snapmirror", then also it is all good.

1) As usual  Snapmirorr will transfer all the data (including all the NTFS folder/file permissions). However, share-level configuration/permissions will need to be created/restore. You could use the script mentioned in the following thread.

2) For testing purpose: You can simply create a "flexclone" on the mirrored-dest and test it out (by sharing out one or two shares just to ensure it is behaving as you expect it to be) before the final cut-over.
