Answer

It depends.

  • If the same IP address as the source is assigned after switchover, the client experience and service accessibility can be made the same in both cases.
  • With identity preserve, this is done automatically.
  • While excluding network configuration, manual configuration is required after switchover.
  • The main differences are in operational overhead and automation.
  • When using identity-preserve, LIF migration might be required after switchover.
