GigaVUE-VM to GigaVUE V Series Migration in GigaVUE‑FM HA

This document provides information and recommendations for migrating your GigaVUE-VM based visibility solution to GigaVUE V Series based solution in VMware ESXi and VMware NSX-V in GigaVUE‑FM HA.

Following are the two primary scenarios for GigaVUE V Series migration in GigaVUE-FM HA:

  • Migrate from GigaVUE-VM to GigaVUE V Series on ESXi platform without any platform change.
  • Migrate from GigaVUE-VM on NSX-V to GigaVUE V Series on NSX-T.
    • Migrate through NSX platform upgrade
    • Migrate through GigaVUE-VM on ESXi

Refer to the following sections for details:

Migrate GigaVUE-VM on ESXi to GigaVUE V Series on ESXi

This section provides the information to migrate your GigaVUE-VM based visibility solution on ESXi to the GigaVUE V Series based solution without changing underlying ESXi platform using GigaVUE-FM HA.

Prerequisites

Before starting the migration ensure the following items:

  • Ensure that you have backed-up your system to recover the configuration on migration failures.
  • Ensure that your GigaVUE-FM HA version is 5.16.00 or above to manage both GigaVUE-VM and GigaVUE V Series based solutions.
  • Ensure that your GigaVUE-FM HA group is healthy with a minimum of three GigaVUE-FM nodes and the active GigaVUE-FM have the required prime license.
  • Ensure that all the migrations are done only on the active GigaVUE-FM.
  • Ensure that you have deployed GigaVUE-VM-based visibility solution on your ESXi platform (without any NSX layer).
    Refer to Configure GigaVUE-VM on ESXi chapter in GigaVUE Cloud Suite Deployment Guide - VMware (ESXi) for detailed information on how to configure GigaVUE-VM visibility solution on VMware ESXi.

Refer to Migrate GigaVUE-VM on ESXi to GigaVUE V Series on ESXi topic for the detailed information to migrate GigaVUE-VM on ESXi to GigaVUE V Series on ESXi

Migrate GigaVUE-VM on NSX-V to GigaVUE V Series on NSX-T

This section describes the approaches and procedures to migrate GigaVUE-VM on NSX-V to GigaVUE V Series on NSX-T on GigaVUE-FM HA.

Following are the two methods to migrate GigaVUE-VM on NSX-V to GigaVUE V Series on NSX-T:

Migrate Through NSX Platform Upgrade

This section provides information and recommendation for migrating GigaVUE-VM to GigaVUE V Series when customer is also upgrading the platform from NSX-V to NSX-T. Our GigaVUE-VM to GigaVUE V Series migration fits into the overall NSX platform upgrade. The topology remains the same during and after the migration process.

Following are the highlights of the recommended migration procedures:

  • Migrate NSX-V platform to NSX-T platform
  • You need not migrate the entire fleet of GigaVUE-VMs to GigaVUE V Series all at once. The migration can be done one host at a time or one group of hosts at a time while the rest of hosts continue to be monitored using GigaVUE-VM to minimize risk and disturbance to production environment.
  • Least interruption to the visibility of your hosts during the migration process.

In Parallel migration and In Place migration are the two approaches recommended by VMware. Refer to How to Migrate from VMware NSX for vSphere to NSX-T guide for detailed information.

In Parallel Migration from GigaVUE-VM on NSX-V to GigaVUE V Series on NSX-T

With this method, NSX-T infrastructure is deployed in parallel along with the existing NSX-V based infrastructure. While some components of NSX-V and NSX-T, such as management, could coexist, compute clusters running the workloads would be running on separate hardware.

The main advantage of this approach is its flexibility. The migration of workloads can happen over a period of time: new workloads are deployed on NSX-T and older workloads are shutdown over time.

Prerequisites

Before starting the migration ensure the following items:

  • Ensure that you have backed-up your system to recover the configuration on migration failures.
  • Ensure that your GigaVUE-FM HA version is 5.16.00 or above to manage both GigaVUE-VM and GigaVUE V Series based solutions.
  • Ensure that your GigaVUE-FM HA group is healthy with a minimum of three GigaVUE-FM nodes and the active GigaVUE-FM have the required prime license.
  • Ensure that all the migrations are done only on the active GigaVUE-FM.
  • Ensure that you have deployed GigaVUE-VM-based visibility solution on your NSX-V platform.
    Refer to Configure GigaVUE-VM on NSX-V in GigaVUE Cloud Suite Deployment Guide - VMware (NSX-T) chapter for detailed information on how to configure GigaVUE-VM visibility solution on VMware NSX-V.
  • Ensure that each of your service cluster has GigaVUE-VMs deployed using either host-based or cluster-based mode.
  • Ensure that your NSX-V connection is in stable state and you have installed NSX-T manager. This NSX-T manager is sharing the same vCenter with the NSX-V manager.
  • Ensure that the VMware's Migration Coordinator Tool is set up correctly.
  • Ensure you have installed a temporary ESXi host and configured it to be part of a cluster managed by NSX-V manager.
  • Ensure that the Gigamon service is configured on the NSX-T manager (through GigaVUE-FM)
VMware provides a Migration Coordinator Tool to assist in migrating from NSX-V to NSX-T platform. Following are the migration steps for all clusters or hosts that are not running the Gigamon service VMs.:
  • Import Configuration
  • Resolve Configuration
  • Migrate Configuration
  • Migrate Edges
  • Migrate Hosts

Refer to In Parallel Migration from GigaVUE-VM on NSX-V to GigaVUE V Series on NSX-T topic for the detailed information to migrate using In Parallel approach.

In Place Migration from GigaVUE-VM on NSX-V to GigaVUE V Series on NSX-T

Another approach to migrating over to NSX-T is using the NSX-T’s built in Migration Coordinator tool. The Migration Coordinator tool, available since the 2.4 release of NSX-T, helps in replacing NSX-V with NSX-T. This tool also imports the existing configuration to apply on the new NSX-T based infrastructure.

The Migration Coordinator tool also supports Maintenance Mode, that allows automatic placement of ESXi host into maintenance mode and vMotion VMs off from the host.

Prerequisites

Before starting the migration ensure the following items:

  • Ensure that you have backed-up your system to recover the configuration on migration failures.
  • Ensure that your GigaVUE-FM HA version is 5.16.00 or above to manage both GigaVUE-VM and GigaVUE V Series based solutions.
  • Ensure that your GigaVUE-FM HA group is healthy with a minimum of three GigaVUE-FM nodes and the active GigaVUE-FM have the required prime license.
