Issue: Customer tries to upload config backup taken from IPv4 Cluster and uploads it on a new Cluster(IPv4 and IPv6), and it fails with below error.
NOTE: Configuration backup taken from IPv4 Cluster cannot be uploaded on Dual mode Cluster.
Resolution: Many Customers request to move the vSZ/SZ cluster from IPv4 to (IPv4 and IPv6)Dual Mode without losing configuration, in this article I will explain how to to move vSZ/SZ from IPv4 towards IPv4 and IPv6 (Dual Mode) without losing existing configuration.
Below devices used for verification of the behavior.
vSZ High Scale(220.127.116.11.935)
From the vSZ GUI, go to the Cluster setting as below
>>>>>Network>>> Data and Control Place>>>Cluster(New Menu)
>>>>>From the Cluster page select Steps in the order mentioned below.
>>>>>In the config option on select IPv4 and IPv6 and click OK.
>>>>>Click Yes to Process, (the controller services will restart after this).
Once all the services are up, the controller will come up in Dual mode with IPv4 and IPv6.
Note: On changing the Cluster mode to Dual IPv4 and IPv6, it cannot be reverted back to IPv4 only(Factory Reset is the only option).
