Recently VMware release is a new update for NSX. The release is NSX Data Center for vSphere 6.4.3 for vSphere.

Important: Previously known as NSX for vSphere, is now known as NSX Data Center for vSphere.

NSX Data Center for vSphere 6.4.3 release is launched just some weeks after 6.4.2 was released. Mostly to fix some of the bugs from version 6.4.2.

Before we continue a small note, this blog post is about NSX-V and not NSX-T. Many times users mix both products. One is for VMware / vSphere (NSX-V), and other is for any Hypervisor (NSX-T), Cloud and physical environments.

Regardless of their System Operation or Hypervisor. Brandon Lee wrote an excellent article here in Vembu regarding the differences between both products.

NSX Data Center for vSphere cannot connect to SSO in an environment with multiple PSCs or STS certificates after installing or upgrading to NSX Data Center for vSphere 6.4.2. Fixed in this NSX Data Center for vSphere 6.4.3 version.

Final thoughts about this new release:

Since the product didn’t have significant changes or improvements, and if you are already running the version NSX Data Center for vSphere 6.4.2, I think only worth to upgrade your NSX if you have multiple PSCs with different Tenant Credentials or multiple STS certificates and facing the bugs listed above. Then you should upgrade to NSX Data Center for vSphere 6.4.3 since bugs are fixed in this last version.

However, if you are running your NSX Data Center for vSphere 6.4.2 without this scenarios and issues, then you should wait for the next NSX version.

If you are running NSX version previous 6.4.2, then yes you should upgrade to the latest version of the latest. In this case, the NSX Data Center for vSphere 6.4.3.

Final note: Don’t forget, before performing any upgrade, backup your NSX and do snapshots of your NSX VMs. Check another article from Brandon Lee here in Vembu, How to configure NSX Backups.
