Is the update order mandatory in the UI?

[rguhr]

In the upgrade UI we have this order:
1. Prepare > 2. Edges > 3. Hosts > 4. NSX Manager

Is it possible to update the hosts first
and then the edges and NSX manager (e.g. on a different day)?

Hi,

No. You cannot skip Edges & upgrade Hosts first. You will have to upgrade each component in the order they are.

Thanks for your answer. It seems that VMware has built in exactly this functionality with VMware NSX 4.0.1.1

Flexibility to upgrade selected TN groups across clusters during NSX upgrade - Previously, NSX upgrade order was fixed to: All Edges → All Hosts → NSX Manager. That meant users had to upgrade all their Edge nodes before they could start upgrading Hosts. Starting with NSX 4.0.1, enjoy more flexibility in upgrading Edges and Hosts. NSX now allows users to create Edge or Host Groups along with the ability to upgrade select Edge or Host Groups at a time, without being locked into the previous sequence. This will help users to better align with their business needs when upgrading their NSX deployments.

However, please keep in mind:

• A Group can contain Only Edges or Only Hosts, NOT a combination of the two.
• While you can move back and forth, upgrading select Edge or Host Groups, the NSX Manager can only be upgraded after all Edges and Hosts have been upgraded.
