Before starting the upgrade, it is important to verify that everything is working normally. If there is an issue on the current working state, it needs to be resolved first before proceeding with the upgrade; otherwise, the upgrade process may fail.
To verify current working state, please ensure you have the following:
- Login credentials against all NSX components
- vCenter Access to manage NSX Virtual Infrastructure
- Console, HTTP/HTTPS, and SSH access to NSX Manager
- Console or SSH access to NSX controllers and service virtual machines
To verify that the current NSX components are working normally, you should check the working state of NSX starting from the access to the NSX Manager, access to the networking and security plugin, and all of the NSX components.
