There is often the situation where you need to change the IP addresses of your NSX-T Managers. For example, you might be changing your IP schema as I am doing currently in my home lab. NSX-T does not have a field to change the IP address of it’s NSX Managers, but you will need to add new NSX Managers with the new desired IP, then gradually delete the old ones. Luckily the process is easy and straight forward as documented below.

Note: While I only have a single NSX-T Manager in my environment as it is a small home lab, usually in a production environment, you always want to maintain 3 NSX Managers active to sustain your NSX-T availability. Try to follow one of the below two approaches to maintain that.

• Scenario A:
  
  • Manager A has IP address 172.16.1.11.
    
  • Manager B has IP address 172.16.1.12.
    
  • Manager C has IP address 172.16.1.13.
    
  • Add Manager D with a new IP address, for example, 192.168.55.11.
    
  • Remove Manager A.
    
  • Add Manager E with a new IP address, for example, 192.168.55.12.
    
  • Remove Manager B.
    
  • Add Manager F with a new IP address, for example, 192.168.55.13.
    
  • Remove Manager C.
    

• Scenario B:
  
  • Manager A has IP address 172.16.1.11.
