Hi,

Try `ssh-keygen -f "/root/.ssh/known_hosts" -R "vcche002"` command then retry the migration.

Hi i am new to this site and also for proxmox system
i have a customer site with standalone HPE rack mount servers each using proxmox virtualization platform, and there is also a new infrastructure Synergy 12000 to be deployed at their site, the customer needs migration of every service from the existing servers to this composable system, does this infrastructure supports proxmox ? or is there a way that the composable built in management software (OneView ) can run as an appliance to proxmox ,like on vmware vsphere ?
