Update Existing Applications wizard will run for every upgrade
Valid from Pega Version 7.1.7
The upgrade process from a PRPC 5.x or 6.x system to Pega 7.1.7 now automatically runs the Update Existing Applications wizard. This may extend the time that the upgrade process takes to complete, depending on the version you are upgrading from and the number of rules in your application.
Upgrading to Pega 7.1.7 with an Oracle database requires new role permissions
Valid from Pega Version 7.1.7
When upgrading or updating from a prior version to Pega 7.1.7, if your system uses an Oracle database, an additional role is required to support the Reversability functionality. In addition to the Oracle privileges specified in the Install Guides, the role SELECT_CATALOG_ROLE is required. Verify that this role is present before beginning the upgrade or update.
Action required by admins for improved search
Valid from Pega Version 7.1.7
Starting November 13, 2014, after updating to or upgrading from a prior version to Pega 7.1.7, your system administrator must manually build all indexes for Elasticsearch before the system can automatically switch from Lucene to Elasticsearch.
It is recommended that you begin this manual re-indexing process for all enabled index types as soon as your update or upgrade is complete. The search landing page refers to Elasticsearch settings; during re-indexing, however, Lucene search continues to function to ensure that there is no interruption in search functions. When planning the re-indexing, be aware that the initial re-indexing requires significant resources on the host node and can be a lengthy process, depending on the number of rules and work objects in your system.
See the Pega 7.1.7 Upgrade Guide for information about manually indexing Elasticsearch.
Updates no longer require redeploying the prweb.war file or the application server-specific EAR file
Valid from Pega Version 7.1.7
Updating from Pega 7.1.7 to later versions of Pega 7 no longer requires that you redeploy the prweb.war file or the application server-specific EAR file.
Note that upgrades from versions prior to Pega 7.1.7 still require that you redeploy these files.
Agents not running after update of EAR-based deployment
Valid from Pega Version 7.1.7
If you update an EAR-file deployment and your update meets both of the following criteria, you must redeploy the prpc_*.ear file for your application server after you complete the update to avoid agent-related errors:
- Updating from Pega 7.1.7, Pega 7.1.8, or Pega 7.1.9
- Updating to Pega 7.1.10, 7.1.11, 7.2, or 7.2.1
If you do not redeploy the prpc_*.ear file, you will see the agent-related issues that are described in the support article Agents are not running.
For information about redeploying, see the Pega 7 Platform Update Guide for your target version of the Pega 7 Platform.
Upgrading to Hazelcast 4.x requires downtime during upgrades to Pega Infinity 8.6
Valid from Pega Version 8.6
Upgrade impact statement
On-premises upgrades of Pega Infinity release 8.4.2 and later to version 8.5.1 or later on Tomcat and PostgreSQL are completed with near-zero downtime. However, upgrading to Hazelcast 4.x requires that you shut down and restart your application server.
What is required to update the application to be compatible with this change?
Hazelcast 3.x is enabled by default. For near-zero downtime upgrades, you do not need to perform any action.
For instructions about upgrading to Hazelcast 4.x, see one of the following topics:
- For near-zero downtime upgrades from Pega Infinity release 8.4.2 or later on Tomcat and PostgreSQL, see "Optional: upgrading to Pega Platform version 8.6: Upgrading to Hazelcast 4.x" in Near-zero downtime Upgrade Guide for Pega Platform version 8.4.2 and later for Tomcat and PostgreSQL.
- For all other upgrades, see "Optional: upgrading to Hazelcast 4.x" in the appropriate upgrade guide.
Improved indexing of StringList and StringGroup property types
Valid from Pega Version 8.6
Search and Reporting Service in Pega Platform™ 8.5 may improperly index StringList and StringGroup property types. As a result, the data model does not include the affected properties.
Upgrade impact
After upgrading to Pega Platform version 8.6, the system requires that the classes with the StringList or StringGroup type are reindexed.
What steps are required to update the application to be compatible with this change?
On the Search Landing Page, manually reindex all the classes that include properties with the StringList or StringGroup types to ensure that all your data is present in the data model. Alternatively, if finding specific instances of classes is difficult, you can reindex all classes in your application.
For more information, see Indexing class data.
