Hi,

 

When changing HA interface, you need to:

 

  • create the new HA Network
  • Create the self IP of the first member
  • Create the self IP of the secondary member
  • move all HA interfaces to the new self IP of the first member in Device configuration (Device Manager member)
  • check all informations are synchronized to the secondary member
  • move all HA interfaces to the new self IP of the secondary member in Device configuration (Device Manager member)
  • check all informations are synchronized to the first member
  • then remove old Self IPs.

If you did not check that IPs are synchronized and remove old IPs too fast, some informations may keep the old IPs.
