For those coming from an NSX-V background, you’ll remember how we enabled east-west traffic by deploying Distributed Logical Routers (DLR). This has changed ever so slightly in NSX-T, with earlier versions using Tier-1 Logical Routers, and in 2.4, Tier-1 Gateways.
That didn’t disappoint! I’ve wanted to visit the North East England VMUG for sometime, so being asked to present at the user group made it all the more special. As I sit here in Newcastle International Airport waiting for my flight home, I thought I’d summarise the event for those who’ve never been to a VMUG event, are thinking of doing so in the future, or are thinking of speaking at a local VMUG.
Welcome to the second article in the series detailing a migration of VMware NSX Data Center for vSphere (NSX-V) to NSX-T Data Center. In this article I focus on the preliminary checks to ensure the NSX-V environment is fit for migration.
In part 1 (VMware NSX-T Data Center Migration – Part 1 – Deploy Manager Appliance) I covered the process of deploying the NSX -T Data Center Manager Appliance, as well as a number of prerequisite tasks required to prepare the new NSX-T environment for the eventual migration (coming in part 3).
In this article I detail a number of preliminary checks within the NSX-V environment (including ESXi hosts, vSphere Distributed Switches, VXLAN configuration, VTEP, NSX Controllers, Edge Services Gateways, etc.) to ensure all is well prior to the migration process itself. Where any issues are identified, these must be resolved prior to the migration process.
