Welcome to part 6 of the F5 to Avi migration series. The previous post in this series discussed the migration method for offline mode. In this post, I will demonstrate migrating complex L4 virtual services.

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

3: Avi Assessment Framework

4: F5 to Avi – Online Mode Migration

5: F5 to Avi – Offline Mode Migration

Not all F5 virtual services can be migrated to Avi using the Avi Conversion Tool. The tool currently has a limitation of migrating L4 virtual services configured for SNI-based routing policy. When you attempt to convert such a VS to AVI format using the conversion tool UI, the tool skips the policies.

Migration of such virtual services is not possible through ACT UI, and you have to do this manually using the converter Python script.… Read More

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:

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

Welcome to part 4 of the F5 to Avi migration series. The previous posts in this series aimed to provide a comprehensive framework for the F5 to Avi migration strategy and planning migration waves. In this post, I will demonstrate how to migrate load balancer objects between the 2 platforms.

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).

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.

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)?

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
