NSX-T host replace.

[abckdc]

Hi All,

We are currently running NSX-T in our 2 Host clusters for Production. The host has now reached EOL and we are replacing the host with a new host with higher compute power. So, now we will need to migrate our current NSX-T scenario to be on to be replaced the new Host. What will be the correct pathway to replace the existing host with a new one keeping the NSX-T configuration intact and with minimal downtime?

The only thing coming into my mind is adding a new host to the same cluster ( enable EVC) and configure NSX-T on the new host ( but what about licensing) keeping all the configurations the same and migrating the VMs to the new host? Once all VMs are migrated depreciate the host from NSX and VMware cluster.

I will be very much grateful for any suggestions.

To replace the old host with a new one while keeping NSX-T configuration intact and with minimal downtime:

Add the new host to the existing cluster.

License the new host for VMware vSphere and NSX-T.

Install and configure NSX-T on the new host like the old one.

Migrate VMs to the new host using vMotion or other methods during a maintenance window.

Test VMs on the new host for proper functionality.

Remove the old host from the cluster and NSX-T environment.
