End of Mainstream Support for OutSystems Platform 9.1

OutSystems continually delivers new capabilities to help customers innovate and differentiate by building digital systems that adapt as fast as business demands. To focus our engineering resources on those innovative capabilities, we establish cut-off dates for when we will stop making changes to older code (End of Mainstream Support). These cut-off dates are typically 2-3 years after the launch of a major version. To that end, we are announcing End of Mainstream Support for OutSystems Platform 9.1 on March 30, 2018.

What Does This Mean?

End of Mainstream Support means that you can still submit support requests with your current subscription, and the OutSystems technical support team will respond according to the contracted support and severity level. However, if a bug is the problem, technical support’s response will not include a fix. In this scenario, problem resolution will only include advice and workarounds. To avoid this situation, we recommend that our customers plan their upgrades before the scheduled end of mainstream support.

OutSystems cloud specifics

If you are on the OutSystems cloud, a timely upgrade is mandatory. Missing the upgrade timelines will result in a mandatory upgrade by OutSystems.

OutSystems will begin mandatory upgrades to OutSystems cloud customers after July 15, 2018. After this date, customers who have not yet concluded the upgrade to a supported version of the OutSystems platform will be scheduled upgrades of all their environments.

Agreeing with OutSystems on an upgrade schedule guarantees that the customer can choose the right time for upgrading the different environments and thereby minimize the impact on your software development activities.

Who Upgrades the Affected Environments?

The upgrade responsibility depends on the type of installation: on-premises, cloud, or hybrid.


If you have an on-premises installation, you are responsible for the upgrade process. OutSystems can provide upgrade services (at a cost) if you wish to have individualized assistance from our OutSystems services team. You may contact your account manager or OutSystems partner for details on the upgrade services offering. You may find more information on how to upgrade on-premises OutSystems Platform in our knowledge base.

OutSystems Cloud

After carefully reviewing our knowledge base documentation, please contact our support team before October 29 to schedule the upgrade before March 30, 2018. Our technical support team upgrades the infrastructure and platform; however, there are additional upgrade activities that you are responsible for, such as assessing the impact of the upgrade on your applications and upgrading these applications.

Hybrid Deployments

If you have a hybrid deployment model that combines on-premises and OutSystems cloud environments, note that your OutSystems platform instances in the Cloud will be scheduled for an upgrade before the End of Mainstream Support date. Please contact our support team before October 30 to coordinate the upgrade of the on-premises and cloud environments at the same time.

What Do You Need to Do?

Start planning your company’s upgrade to OutSystems 10 for the next level of rapid delivery of high-profile enterprise and offline mobile applications. By upgrading, you will benefit from the enhanced capabilities of the newest OutSystems releases and continue taking advantage of OutSystems support and maintenance.

To help you design an effective upgrade strategy, we’ve published an OutSystems Upgrade Guide. If you have any questions about this notice, contact your OutSystems Partner or account manager.
