Upgrade OutSystems Platform


Upgrade OutSystems Platform

This article guides in how you can upgrade your OutSystems Platform to a new major or minor version. You'll be able to assess the upgrade process, understand its impacts, and plan it accordingly. 

Before you start

To learn more about a specific release, check the What's New document for that version:

To assess the impact an upgrade to a new major version may have in your applications, check the Side Effects and Breaking Changes documents:

Be sure to read all the documents that might impact your upgrade. For example, if you're upgrading from OutSystems Platform 8 to 10, read the breaking changes for the versions 9, 9.1, and 10.


Upgrading an environment or a set of environments to a new OutSystems Platform major release should always follow the staging lifecycle of the applications in that infrastructure. If your infrastructure has a dedicated Management Console (Lifetime) environment, then you first need to upgrade that environment, otherwise, just upgrade each environment by the order of your staging procedures. Most of our customers upgrade their environments in the same order they push their developments to Production, for example:

Development > Testing > Pre-Production > Production

But you have the freedom to choose the order that is most convenient to you and your customers. Sometimes, to best coordinate with the development teams and on-going projects, one can start with other non-production environment (.e.g., pre-production) to fully validate the applications upgrade, and then upgrade the Production environment. Only after, upgrade of the Development environment according to the development teams delivery sprints. Bottom line is, you should always upgrade and test your applications in a non-production environment before proceeding to production environment.

The overall process of upgrading an OutSystems Platform environment is:

  1. Upgrade the Platform Server of the environment;
  2. Upgrade the development tools (Development client tools in the downloads page) of developers who publish applications in the environment;
  3. Upgrade all the modules in the environment. In the Development environment, use a solution containing all extensions and eSpaces to update all modules at once in Service Center; in all other environments, stage all the applications from the already upgraded environment to the next environment.
