Migration from Gazebo classic to Ignition Gazebo

Hi community! :fire:

With Gazebo 7 reaching end of life, we’d like to bring some tips for how to migrate your Gazebo classic projects to Ignition Gazebo!

First of all, if you’re new to Ignition, check out the get started tutorial and the introductory tutorial video series.

Choosing versions

Gazebo classic currently has 2 supported versions:

  • Gazebo 9: until January 2023
  • Gazebo 11: until January 2025

Ignition also has 2 supported collections, and an upcoming one:

  • Citadel: until December 2024
  • Dome: until December 2021
  • Edifice: to be released on March 2020

Among these versions, Gazebo 11 and Ignition Citadel are the most compatible. They use lots of the same underlying dependencies (libSDFormat 9, Ignition Math 6, Ignition Transport 8…), so it’s possible to write code that is shared among them, even if the plugins themselves need to be different. These versions also have similar support schedules.

Therefore, if you’re doing a staged migration and want to maintain both a classic and an Ignition implementation for a while, Gazebo 11 + Citadel is a good combination to choose. On the other hand, if you’re doing a one-time migration and never looking back at Gazebo classic, then going from any version to any other version should be ok.

Another thing to keep in mind when choosing a version are the features available in each one of them. The links below should be good references:

Migrating

Once you’ve chosen a version, check out the following guides according to your use case.
