Planning considerations for upgrades of Pega Infinity release 8.4.1 and earlier
Pega collaborates with you and helps you plan and structure you upgrade approach. Pega encourages you to assess and decide on when you adopt new features and functionality available in Pega Infinity. Pega is committed to the highest software upgrade quality so that you experience an automated upgrade with less downtime and fewer post-upgrade steps than earlier versions of Pega Platform. Pega uses the following feature development standards to ensure it seamlessly integrates with applications that are guardrail compliant:
- Backwards compatibility for Pega Platform and Pega application software changes, ensuring trouble-free software upgrades.
- Fewer required post-upgrade steps in most Pega software applications. The upgrade process includes a post-upgrade, feature adoption phase for completing mandatory and optional post-upgrade steps, recommended configuration changes, verification steps, or for adopting new features in your application.
- Identification of new features or performance improvements with a potential for upgrade impact. To see the changes with known upgrade impact, see Pega Platform changes with upgrade impact.
- Development of analytical tools with which you can assess the upgrade impact
on your application to ensure that it is ready for an upgrade. Examples
- Pre-Upgrade Check for Pega Marketing and Pega Customer Decision Hub
- Pega Customer Service Upgrade Checker
- Pega Sales Automation Upgrade Checker
For Pega Platform, Pega provides a pre-upgrade tool that identifies the rules that you have customized in your application to understand the impact of the upgrade; your are expected to use the results to retrofit these rules after the upgrade. As a best practice, do not overwrite or customize Pega rules. For more information, see Pega Upgrade Tools.
For any software upgrade to Pega Infinity, Pega uses a two-phased software upgrade process, so that you can adopt the latest performance and security improvements without affecting your existing Pega applications. This two-phased life cycle approach provides flexibility to your adoption of the latest features and enhancements in the latest version into your Pega application:
- Basic upgrade
- Upgrades Pega Infinity rules to the latest version, with minimum disruption. Typically the Basic upgrade phase take you about four weeks to complete. This phase allows you to make any necessary application changes to ensure functional correctness and upgrade compliance. You can adopt the latest performance and security improvements and can test existing functionality using your current testing processes. This phase excludes adopting features of the new version of the Pega Infinity to ensure a near zero-downtime upgrade of the production environment.
- Feature adoption
- After the Basic upgrade is complete, you use this phase to take advantage of the latest Pega Infinity and application features using your standard DevOps process.
This phased approach requires that you maintain a standard, consistent DevOps approach so that they can assess the effect of the latest Pega PlatformPega Platform and Pega application capabilities and plan your new feature adoption strategy across your environments following your Pega Infinity upgrade. This standardization includes the following structure:
- You configure your staging environment similar to, but not necessarily the
same as, your production environment. This requires that:
- The rules and data schema DDL are the same as the production rules and data schema DDL.
- The rules content is identical except for production environment specific configurations.
- There is appropriate test data in the Staging environment; copying production data is not allowed.
- You must already use a deployment pipeline with a minimum number of development, staging, and production environments and use the pipeline to promote the latest application functionality to your production environments. You use Deployment Manager for your standard deployment pipeline. For details, see Using Deployment Manager for model-driven DevOps.
- Pega Cloud does not support modifying the production level of any environment. If you modified the default production level of your environment, it will be reset during the upgrade process. For details, see Specifying the production level.
The Pega Cloud upgrade experience
Pega uses a standardized software upgrade process that provides you with an upgraded, cloned staging environment for a 30-day trial period. On this cloned environment, you test by using existing test suites, which minimizes efforts and shortens the upgrade life cycle environments. You must schedule the provisioning of this cloned environments when initiating your upgrade through the My Pega Cloud portal. After your cloned environment has been provisioned, you can access the Pega-provided URL to the cloned, staging environment. On the Home tab, in the Upgrades tile, click View details. The UAT stage screen displays the cloned, staging environment URL.
For more information on managing upgrades in the My Pega Cloud portal, see Upgrades.
The standard Pega Cloud software upgrade process integrates the latest Pega automation technology to support seamless adoption of the latest Pega Infinity features and improvements across environments using your development pipeline.
The following limitations and expected behaviors within your environments apply but are not limited to a your software upgrade experience:
- During the environment upgrades, you experience environment downtime, during which time you cannot access Pega applications. Pega Cloud Services makes a reasonable effort to minimize this downtime.
- Any data saved to the database before the upgrade process is never lost during the upgrade process. Throughout the Pega Cloud Services software upgrade process, Pega does not use the Pega application sample data.
- User sessions are not persisted: active users might be logged off during the environment restart.
- Reschedule any upcoming activities, such as job schedulers, before Pega initiates the upgrade process.
- If you upgrade from Pega Platform version 8.2 or earlier: stop all background processes before Pega initiates the upgrade process and restart the stopped processes after Pegasystems, Inc. completes the upgrade process. To complete the pausing and subsequent resuming of these background processes, see Managing background processes during upgrades and patches.
- If you upgrade from Pega Platform version 8.3 or later: The upgrade process waits up to 30 minutes for any activity that is running in the background to finish its work; if the activity is not finished after 30 minutes, the background process is terminated. Review these application development best practices to ensure that your background processing takes only several minutes to complete:
- Existing mashups must be migrated; beginning in Pega Platform 8.5.1, Pega Web
Mashups include a channel ID in the mashup code for validation with your
mashup server. Create new mashup code on your upgraded, cloned environment
running release 8.5.1 or later so the mashup rule form includes a Mashup
channelID that is automatically included in your application testing rule in
your upgrade pipeline. To create a new mashup, see Creating a mashup. Be sure to
update existing website configurations with the new mashup code.
For more information about migrating mashups, see Migrating existing mashups.
In addition, you must migrate your existing mashups; beginning in Pega Platform 8.5.1, Pega Web Mashups include a channel ID in the mashup code for validation with your mashup server. Create new mashup code on your upgraded, cloned environment running release 8.5.1 so the mashup rule form includes a Mashup channelID that is automatically included in your application testing rule in your upgrade pipeline. To create a new mashup, see Creating a mashup. Be sure to update existing website configurations with the new mashup code.
Details of the new Pega Cloud Services software upgrade process
The Pega Cloud Services major software upgrade process requires that Pega and you coordinate your efforts throughout the upgrade process. After Pega receives your request for an upgrade to Pega Infinity, the process phases are broken into discrete steps based on the responsibility model:
- Pega clones a staging environment identified by
you in your upgrade request and upgrades this cloned environment to the latest
Pega Platform and application software. This upgrade
includes all the declared cumulative patches and critical hotfixes as defined in
Pega maintenance and types of system updates. The clone maintains
the application and data from the staging environment with the following
- Decision data store (DDS) datasets are not copied. For details, see Pega Cloud cloning limitations in Customer Decision Hub environments.
- Kafka data sets are not copied; custom or internal queue processors automatically start on the cloned environment; and new topics are created in Kafka on first use. For details, see Pega Cloud cloning limitations for stream data sets and environment stream tiers.
- Archived data, case attachments, and SFTP data, because these are maintained in the Pega Cloud File storage repository and the cloned environment gets its own, new repository. To configure archiving on the cloned environment, see Improving performance by archiving cases; to configure file listeners on the cloned environment, see Configure a file listener associated with a storage repository.
- In Deployment Manager, your migrate rules from the upgraded cloned, staging environment to the production environment for each application using an upgrade pipeline. The upgrade pipeline includes two product rules that contain any upgrade fixes and confidence testing assets along with all required data instances to test the application. For details, see Configuring upgrade pipelines.
- You perform application compatibility testing and validation on the cloned staging environment for up to 30 days, when they can make any changes or fixes necessary to verify expected application functionality while using the new version of Pega Infinity. Within this period, you complete your regression testing and then indicate your readiness to consent to upgrade your production environment. During this testing phase, you can complete your regression testing on the upgraded, cloned staging environment. Helpful resources include:
- You perform any of the following steps that apply on the production
- For applicable applications that run Pega Platform version 7.3.x or earlier, perform a limited number of pre-upgrade steps in coordination with Pegasystems, Inc. Review the software upgrade communication from Pega for guidance. For details, see: Completing pre-upgrade tasks for Pega Marketing 7.4 and earlier running on Pega Cloud.
- Reschedule any upcoming activities, such as job schedulers, before Pegasystems, Inc. initiates the upgrade process.
- If you upgrade from Pega Platform version 8.2 or earlier: Stop all background processes before Pegasystems, Inc. initiates the upgrade process and restart the stopped processes after Pega completes the upgrade process. To complete the pausing and subsequent resuming of these background processes, see Managing background processes during upgrades and patches.
- If you upgrade from Pega Platform version 8.3 or later: The upgrade process waits up to 30 minutes for any activity that is running in the background to finish its work; if the activity is not finished after 30 minutes, the background process is terminated.
- Pega upgrades your respective production environment during your standard maintenance window.
- You perform any of the following required steps that apply to your applications
on the production environment as detailed in the following articles:
