1. During the migration process, the network latency between the source and the HCI platform(where the destination is located) must be within 50ms,
and the packet loss rate is within 5%.
2. To meet the migration requirements of different network environments, the migration agent of the SCMP supports two connection modes:
• • For the Actively Connected Agent migration mode, point-to-point migration will connect to ports 80 and 20000-20047 of the SCMP. While for HA backup or backup migration, it will connect the ports 80 and 20000- 20003 of the SCMP. If there is a firewall or DNAT in the connection link, it is necessary to allow these ports to be accessed.
• • For the Passively Connected Agent migration mode, it will be the SCMP access to the port of the migration agent. The default port for Connected TCP Port is 3345, and it can be changed when downloading the migration agent. If there is a firewall or DNAT in the connection link, it is necessary to allow access to these ports.
3. For agentless VMware migration, the network needs to meet the following requirements:
• • SCMP needs to be able to access the TCP port 443 of VMware vCenter and the TCP port 902 of the ESXi server.
• • The network between the source VMware vCenter and SCMP must be reachable.
• • The network between the source VMware ESXi host and SCMP must be reachable.
• • If the ESXi host uses a domain name to connect to vCenter, the domain name of the ESXi host must be able to be resolved by SCMP.
• • The VMware account used needs permission to back up the virtual machine.
