VMware NSX 4.0.0.1 has now been release the product is now no longer called NSX-T but VMware NSX. Yes it says version 4.0.0.1 as to what happened to 4.0 we’ll never know 😀
This release seems to add a lot of IPv6 functionality. Interestingly it seems the Native Load Balancer has not yet been removed from the product. They are recommending that when migrating from NSX-V to VMware NSX its done as a two stage migration first to the native LB and then to the NSX ALB. Honestly I think a lot of customers that are still doing V to T (VMware NSX) migrations will just leave the LB in NSX until they are forced to move it.
Upgrade requirements are vSphere and vCenter 7.0 as a minimum, full release notes can be found on the link below.
