I am working on data migration from an old storage ( that supports it seems greater UTF like 32 ) to netapp ontap system ; some of the files can not be copied ; i tested it works with new volumes that are utf8mb4 ( default is utf8 based ) .

Question is can the default language be changed to utf8mb4 ?

The command fails but it also states to contact support ( that might be considered as a chance to change it but assisted by netapp ) .

"AFFA250::> vol modify -vserver CIFS_SVM -volume link1 -language utf8mb4

Error: command failed: Changing the language of a volume is not supported. Contact technical support for assistance."

what is the current volume language and your ONTAP version?

#

because it actually is supported to change the volume language from (anything).UTF-8 to utf8mb4 in ONTAP 9.7P1 and newer. But you need to be on a language that has the .UTF-8 suffix for that to work.

Can the volume language be changed after creation in ONTAP?

#

the trick is to do a set diag before, then it allows the change (but only a change from *.UTF-8 to utf8mb4, nothing else)
