Upgrade vCenter 6.0U3 to 6.5U1

Quick question.

I am upgrading vcenter to 6.5U1 using the ui installer.

Everything proceeds as normal however right before the data migration I receive an alert stating the there "may be" extenstions that may not work after the upgrade. Specifically NSX and Openstack NGC.

I have review all the interoperability matrices and Openstack 3.1 as well as NSX 6.3.1 is compatible with vcenter 6.5U1

I have since cancelled the upgrade pending advice here as the last thing I want is to do is have VIO offline.

Am I ok to proceed or do I need to obtain upgraded extenstions from somewhere ?

Lastly we are moving our full environment to 6.5 over christmas and I will be upgrading each host one by one while using vmotion to move vm around so as to not affect uptime. Is this a perfectly ok method ? Can two differing ESXi hosts with differing versions be in the same cluster ? I will have 12 servers to do so I expect it to take a day as long as I can have the upgraded hosts with the un-upgraded hosts in the Compute and Management Clusters while they wait to be upgraded.

Thanks

Dear Ben,

                As far as the error message you can ignore it , that is just a warning so that you don't end up with loosing the product feature/functionality if it is unsupported in the upgraded version. Again this is not specific to those plugin,if we have any third party plugin we will get those alerts. Upgrading servers one by one is the correct approach, also it depends upon the downtime and features used and number of workloads involved. Not in every scenario we can do upgrade for 2-3 servers in one shot by migrating the servers to another node(vSphere design matters) . Usually i prefer picking one management and one compute host and perform the upgrade,if you are using collapsed cluster it really doesn't matter as long the server specs are equal for all.  So start with VC upgrade(take a snapshot and backup) and perform Host upgrade followed by NSX upgrade(if it is required) and once the upgrade is completed you may delete the snapshot.

Note: Switch the DRS to manual mode and perform the VM migration activity  and put to back to automatic mode after the full sweep upgrade.
