Upgrading NSX Data Center for vSphere Manager to 6.4.4

Recently, I have been working on the home lab and getting various components upgraded to the latest and greatest. In working on a nested VMware vSphere vSAN 6.7 Update lab for VMware Horizon 7.7, I decided also to get NSX updated in the lab as well. In this particular environment, I had only deployed an NSX Manager and connected it to the vCenter Server for the nested lab. However, I had not installed the NSX vibs on the hosts or deployed any controllers as of yet. For this particular “upgrade” I only needed to upgrade the NSX Manager. I was coming from NSX 6.4.1 and would be upgrading to the NSX Manager version 6.4.4. In this post, we will take a quick look at what’s new in NSX Data Center for vSphere 6.4.4 as well as the process of upgrading a legacy NSX Manager to version 6.4.4.

What’s New in NSX Data Center for vSphere 6.4.4?

Before getting into the new features, the NSX Data Center for vSphere 6.4.4 is a release that resolves several customer related bugs. Just a few of those issues that have been resolved with 6.4.4 are issues related to GI SVM memory limits with high network throughput. High memory observed in teh GI SVM. Then, looss of connectivity to the NSX Manager may also occur. When flow collection is turned on in NSX, some customers have observed a purple screen on the host. This has resulted in the loss of VMs data. Another issue resolved is an error that is thrown when there is no port on the physical switch. If a physical switch on a hardware gateway has no port, NSX throws an error when trying to get the port from the switch. Another issue resolved is after the NSX manager reboot, NSX VIBs installation task is shown as continuously running in the UI on the Host preparation tab.

Now, what’s new? VMware NSX Data Center for vSphere 6.4.4 contains new functionality updates in this release for the HTML 5 vSphere client. Now, with NSX Data Center for vSphere 6.4.4 and the HTML 5 vSphere client, you can now manage many of the features of Logical Switches, Edge Appliances, Edge Services (DHCP, NAT, Edge Certificates, Edge Grouping Objects, etc. What functionality still needs to be managed from the web client and not the vSphere client (HTML 5) client? Below is a listing of the functionality that still needs to be managed in the web client (flex client).

Upgrading NSX Data Center for vSphere Manager to 6.4.4

The upgrade of NSX components involve upgrading the NSX Manager, then the controllers, and then upgrading the NSX Host cluster. On vSphere 6.0 and later, once you have upgraded from NSX 6.2.x to NSX 6.3.x or later, any subsequent NSX VIB changes do not require a reboot. Below, we are logging into the NSX Manager interface.
