Symptoms

Performing domain-to-domain migration on the UI fails with the below error:
 
Error observed from UI

Cause

VNXe Unisphere was initially based on Adobe Flash Player which is no longer supported in browsers. VNXe Unisphere was migrated to HTML5 starting with OE version 3.1.12 and later. See article Dell VNXe: Alternative for Adobe Flash Player to access Unisphere for details.

Domain-to-domain migration through the UI is a limitation of the new HTML UI and is identified as a Flash-to-HTML regression.

Resolution

Since the product is End of Service Life (EOSL) by January 2023, no further releases or fixes to this issue are expected. Valid workarounds are available.

There are two workarounds to perform this activity:
  • Make the NAS server stand-alone from the UI before joining the new domain.
Note: This has an additional risk of losing the permissions set on the shares.
  • Use the Uemcli command to migrate between domains:
  1. Identify the Common Internet File System (CIFS) ID of the server to be migrated using the below command:
uemcli  /net/nas/cifs  show
  1. Use the CIFS ID obtained in step 1 to run the below command:
uemcli -u <> -p <> /net/nas/cifs -id <CIFS_Server_ID> set -currentUsername <> -currentPasswdSecure -domain <New Domain> -newUsername <> -newPasswdSecure
For further options on the above command, see the VNXe Series CLI User Guide, section "Change CIFS server Settings"
 
Note: Ensure that all pre-requisite changes are made to the CIFS server prior to performing domain-to-domain migration, such as adding new Domain Name System (DNS) details to the CIFS server, network changes, and connectivity, and so forth.
