Move SMB3 data to a new filer, svm and volume

[shadow echo]

Hi all,
In the process of migrating data from an SMB3 share on oldfiler, using name (SVM-CIfs name registered in AD) datasmb31

After migrating, I brought down the data lifs on the old filer and added them to the smb svm on the new filer.
The SVM is registered to the same domain with a different name.
I can access the data over the \ip\share, but not over \datasmb31\share.

Do I need to go through this KB?

Any help would be appriciated!
Thanks - Martijn

are you getting an error, such as "a device attached to the system is not functioning" or anything else?
Is the DNS updated and cache flushed?
Do you have an alias added to the SVM?
https://docs.netapp.com/us-en/ontap-cli-9111/vserver-cifs-add-netbios-aliases.html

also, have you checked on the filer itself to see if it is connecting to LDAP/etc and authenticating properly

NOTE, this document is a guideline for our specific setup and some of the steps might not be necessary for you.. such as enabling/disabling AES and other options.
It's just a GUIDELINE of some basics

As I migrate the ip, I think that is not necessary

Yes, that works fine

I will add the alias! Thanks

I remember having an almost identical issue and it was related to SPNs (service principle names) in windows/AD. I think you have to add an SPN entry on the computer object that is created when you join the new SVM to the domain. The windows command is 'setspn'. I wish I could remember the documentation I used at the time.. but I think you just need to add "datasmb31" as an SPN entry on the CIFS computer object in AD.

We are going to try the migration again tonight. Keep you posted!

Ah, I expected Something Like this.... Great you figured it Out

Worked like a charm. Decided to use: https://kb.netapp.com/on-prem/ontap/da/NAS/NAS-KBs/Is_it_possible_to_change_a_configured_CIFS_servers_NetBIOS_name_in_ONTAP_9

Would SVM Migrate be a better approach in the future? Pick up and move an entire SVM to a new cluster and cutover pretty much live. Its insane how good it is. I've used it a number of times now and works great!

Absolutety. Would always be my first option. Source system was 9.8 in this case!
Thanks for your addition!

Ah bummer ... yeah it's frustrating that you need 9.12.1+ to move CIFS SVMs. For those before that release I'm just using SVM-DR, provided the source is just serving CIFS or NFS.
