# Upgrade SLA to 2011 engine

# Upgrade SLA to 2011 engine {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
You can upgrade SLA processing to use the 2011 Engine.

## Before you begin

Role required: admin

## About this task

The service level management plugin was enhanced with the ability to script the condition rules for SLA transitions, giving control over how the conditions in an SLA Definition are used. Please review the documentation before enabling the enhancements to understand how the new engine will impact existing customizations  
Note:  
Activating the 2011 SLA engine will deactivate all business rules on the `task_sla` table (except for the rule Task SLA Empty Schedule Warning, which is part of the 2011 engine). If you have added any additional business rules or customized the default business rules, these will not be automatically deactivated. So you should review these customizations, and manually deactivate such business rules, before making this change.

The default Process SLAs rule on the `task` table will also be
deactivated, so any customizations to this script must be incorporated into the new
SLA engine.

In addition, breach information is removed from the
Stage field, and stored in the new Has breached field.

To enable the new
functionality:

## Procedure

1. Navigate to AllService Level ManagementSLA Properties.
2. Change the following property from 2010 to 2011:  
   By default, the 2011 Engine sets the Stage field to
   In Progress, shaded red to indicate the breached
   status, and sets the Has Breached field to true. The
   SLA continues to run until the stop conditions are met.
