Nutanix has issued another end of sales document for Nutanix Mine. They want existing customers to migrate to Nutanix Unified Storage (NUS). There is currently no migration path for Nutanix Mine customers. They will have to build out a new cluster and copy their backups to the new cluster that is licensed for Nutanix Unified Storage. Please have customers reach out to the Nutanix reps to acquire appropriate licensing upgrade paths. I have attached the current EOS document below. Once the Veeam Nutanix Mine online documentation is updated it will also reflect this new document attached. The last supported version for Mine v4 will be Veeam Backup and Replication v12.x.
