Meet the prerequisites for migration

Last published : Sep 11, 2026
Before you start the migration, ensure that the following prerequisites are met:
  • The cluster is running with LLT configured over UDP using IPv4.
  • The broadcast address is set explicitly for each link.
  • For nodes in different subnets, the netmask is set so that the nodes can access the subnets in use.
  • Each NIC has an IPv6 address that is configured before configuring LLT.
  • Each link has a unique not well-known UDP port.
  • IPv6 is configured on all the nodes before you perform the migration. That is, the nodes must have both IPv4 and IPv6 addresses configured.
