F5 to Avi Load Balancer Migration – Part 5: Offline Mode Migration

manish_jha86

Welcome to part 5 of the F5 to Avi migration series. The previous posts in this series discussed the online mode migration of the load balancer from F5 to Avi. In this post, I will demonstrate the offline mode migration.

If you are not following along, I encourage you to read the earlier parts of this series from the links below:

1: Introduction to F5 to Avi Load Balancer Migration

2: F5 to Avi – Migration Strategy Framework

3: Avi Assessment Framework

4: F5 to Avi Online Mode Migration

Offline migration is typically needed when you want to migrate F5 BIG-IP configurations to AVI without direct connectivity between systems or in air-gapped environments. To convert the F5 objects, you manually upload the F5 configuration file (bigip.conf), certificates, and keys to the conversion tool.

To perform offline migration, login to the conversion tool and navigate to the Migrate tab, and click Start.… Read More

F5 to Avi Load Balancer Migration – Part 4: Online Mode Migration

Avi Load Balancer Conversion Tool

To migrate load balancer objects from F5 to Avi, VMware provides a migration tool called “Avi Load Balancer Conversion Tool (ALBCT),” a UI-based conversion tool that automates and simplifies migration of existing F5 load balancer configurations to the Avi Load Balancer platform.The conversion tool helps you:

  1. Import configuration files from existing load balancers (F5).

F5 to Avi Load Balancer Migration – Part 3: Identifying Migration Candidates

manish_jha86

Welcome to part 3 of the F5 to Avi migration series. Part 1 of this series discussed use cases of Avi migration, and part 2 dived into the migration framework that you should follow for a successful error-free migration.

If you are not following along, I encourage you to read the earlier parts of this series from the links below:

1: Introduction to F5 to Avi Load Balancer Migration

2: F5 to Avi – Migration Strategy Framework

Overview

Not all F5 virtual services and configurations are equally suited for immediate migration to Avi. A strategic assessment helps prioritize migrations, manage risks, and allocate resources effectively. In this post I will try to provide a comprehensive framework for evaluating F5 objects and determining migration candidacy.

Step 1: Understand the Goal of Migration

Before identifying good candidates, clarify the purpose:

  • Are you moving to reduce licensing costs (F5 → NSX ALB built into NSX or vSphere+ licensing)?

F5 to Avi Load Balancer Migration – Part 2: Migration Strategy Framework

manish_jha86

In the first post of this series, I discussed the top reasons why an organization wants to move from F5 to Avi load balancer. In this post, I will discuss the migration strategy for a successful migration.

To migrate from F5 to Avi Load Balancer, VMware provides a free Avi Load Balancer Conversion Tool (ALBCT) that automates the translation of F5 BIG-IP configurations. The migration process involves using this tool to convert the F5 load balancer configuration and then cutting over traffic to the Avi-based environment.

Migration Strategy: An Eight-Stage Approach

The key to successful migration is meticulous planning, comprehensive testing, and leveraging Avi’s conversion tool to automate complex configuration transformations. With proper execution, organizations emerge with a modern, scalable, and easier-to-manage load balancing platform that supports their digital transformation initiatives.

The image below lists the various stages involved in the strategic planning for a successful migration.

Stage 1: Planning and Assessment

Before any technical work begins, thorough planning is essential.… Read More

F5 to Avi Load Balancer Migration – Part 1: Introduction

manish_jha86

Introduction

In today’s digital-first world, enterprises are under constant pressure to modernize infrastructure, adopt hybrid and multi-cloud architectures, and deliver applications faster.As enterprises accelerate their digital transformation journey, legacy load-balancing infrastructure is becoming a bottleneck. The rise of cloud-native applications, containerization, and the need for operational simplicity have prompted many organizations to evaluate modern alternatives.

F5 BIG-IP, while robust, lacks the agility, automation capabilities, and cloud-native architecture that modern applications demand. On the other hand, Avi Load Balancer, a software-defined, cloud-native alternative, offers organizations the flexibility to evolve their infrastructure with minimal disruption.

In this blog, I will cover the key use cases driving migration from F5 to Avi Load Balancer.

Use Cases for F5 to Avi Migration

Migrating from F5 to Avi helps organizations modernize their application delivery infrastructure, reduce operational complexity, and achieve cloud agility. Below are some common use cases for F5 to Avi migration.

1. Cloud and Multi-Cloud Strategy Enablement

Organizations are adopting multi-cloud architectures to avoid vendor lock-in and leverage best-of-breed services across providers.… Read More

VCF-9 – Part 10: Deploy VKS with NSX VPCs

manish_jha86

Welcome to part 9 of the VCF-9 series. The previous post in this series discussed VPC networking in greater detail. In this post, I will demonstrate how to deploy vSphere Kubernetes Service (VKS) in an NSX VPC.

The NSX VPC feature is not new and was first introduced in NSX 4.0. NSX VPCs provide multi-tenancy capabilities, as they offer networking and security services to multiple tenants that are completely isolated from one another. Access to networking constructs (T1 gateways, segments, etc.) is controlled via RBAC policies, and limits are enforced by assigning quotas to the objects that can be created inside a tenant.… Read More

VCF 9 – Depot Configuration and Binary Management in VCF Operations

manish_jha86

In older versions of VCF (4.x & 5.x), before you deploy any of the Aria suite components, you have to download the binaries online or download the binaries manually and upload them into VMware Aria Suite Lifecycle, followed by binary mapping. Then, you can leverage these binaries to install, upgrade, or patch products from the Aria suite.

In VCF 9, this functionality has been moved to the unified VCF Operations component. All VCF fleet-related configurations/tasks are now performed through the VCF Operations. Using VCF operations, you can configure an online depot (token-based) or an offline depot for binary management. A depot serves as a source for downloading installation, upgrade, and patch binaries. You must set up a depot before downloading and installing components like VCF Operations for Logs and VCF Operations for Networks.

Only one depot connection can be ACTIVE at a time. If a depot is already ACTIVE, you must disconnect it before switching the depot to Online or Offline.… Read More
