Upgrading Rocket Chat and MongoDB: A Step-by-Step Guide
Introduction
In this guide, we will walk You through the process of upgrading a server running an outdated version of Rocket Chat to the latest release. We will also cover the upgrade path for MongoDB, which is the database management system used by Rocket Chat. By following these steps, you will be able to safely and efficiently upgrade your Rocket Chat environment to the latest versions.
Setup Explanation
Before we dive into the upgrade process, let's first understand the setup. The setup consists of four servers, with three servers forming a MongoDB replica set. The Rocket Chat server is running version 1.0.0, while the MongoDB cluster is running version 4.0 with the Map storage engine. Our goal is to upgrade Rocket Chat to version 6.3.7 and the MongoDB replica set to version 5.0 using the WiredTiger storage engine.
Upgrade Path Overview
Rocket Chat recommends avoiding skipping major versions during an upgrade. Therefore, we will adopt the following upgrade path: from version 1.0.0 to 1.3.3, then to 2.4.4, followed by 3.8.7, and finally version 4.8.7. After this, we will address the MongoDB upgrade path, keeping in mind that MongoDB has its own migration path.
Upgrading Rocket Chat to Version 1.3.3
To begin the upgrade process, we will first update Rocket Chat to version 1.3.3. We will modify the Docker Compose file to specify the target version, stop the existing container, remove it, and then Create a new container with the updated version. This upgrade will preserve all user data, including rooms and messages.
Upgrading Rocket Chat to Version 2.4.4
After successfully upgrading to version 1.3.3, we will proceed to upgrade Rocket Chat to version 2.4.4. The process will follow the same steps as before, modifying the Docker Compose file, stopping the container, removing it, and creating a new container with the updated version. Again, all user data will be preserved.
Upgrading Rocket Chat to Version 3.8.7
Once version 2.4.4 is installed, we will Continue with the next upgrade to version 3.8.7. Following the same procedure as before, we will modify the Docker Compose file, stop the container, remove it, and create a new container with the updated version. All user data, including messages, rooms, and users, will remain intact.
Upgrading Rocket Chat to Version 4.8.7
After version 3.8.7 is successfully installed, we will proceed with the upgrade to version 4.8.7. The upgrade process remains consistent: modifying the Docker Compose file, stopping the container, removing it, and creating a new container with the updated version. All data will be preserved as we move closer to the latest version.
Upgrading MongoDB to Version 4.2
At this stage, we will switch our focus to the MongoDB upgrade path. Before installing Rocket Chat versions above 6.0, it is necessary to upgrade the MongoDB version. We will upgrade the MongoDB cluster to version 4.2, noting that the Map storage engine is no longer supported. We will follow the MongoDB documentation for detailed instructions on how to update to WiredTiger, which is the recommended storage engine.
Upgrading MongoDB to Version 4.4
Once MongoDB is updated to version 4.2, we will proceed to upgrade to version 4.4. Following the same procedure as before, we will modify the Docker Compose file, stop the container, remove it, and create a new container with the updated version.
Upgrading MongoDB to Version 5.0
Lastly, we will upgrade MongoDB to version 5.0. This upgrade is crucial before installing Rocket Chat versions above 6.0. Again, we will modify the Docker Compose file, stop the container, remove it, and create a new container with the updated version.
