Important steps before installing the K2 blackpearl (4.7) April 2022 Cumulative Update

 

Admin consent recommended before upgrading with Nintex K2 blackpearl (4.7) April 2022 Cumulative Update

 

Microsoft is deprecating Azure AD Graph API in June 2022, and as of June 30th, 2020, stopped adding new features to the API. See these Microsoft articles for more information:

Microsoft strongly recommends upgrading to Microsoft Graph API to access Azure AD APIs as well as APIs from other Microsoft services. K2 OAuth resources requiring access to the https://graph.windows.net API (AAD Graph), must be upgraded to use https://graph.microsoft.com (Microsoft Graph) as part of the migration from AAD Graph to Microsoft Graph. Nintex K2 blackpearl (4.7) April 2022 Cumulative Update includes the code fixes necessary for this migration. For more information on migrating apps, see the Microsoft article App migration planning checklist.

After the installation of the Cumulative Update, the OAuth resources that require access to AAD Graph API will be updated to use Microsoft Graph API instead. This will affect the workflows using the Azure Active Directory broker. These workflows can enter a failed state if the workflow executes a step that uses the broker after upgrade, but before a Global administrator in your organization re-consents to the Microsoft Graph permissions. These workflows will have to be manually repaired after upgrade and re-consent.

K2 blackpearl (4.7) April 2022 Cumulative Update

 

The  K2 blackpearl (4.7) April 2022 Cumulative Update contains updates and fixes for issues reported in K2 Five (5.4). K2 recommends keeping your K2 environment updated by installing the latest cumulative update, and that you test this update before you deploy to a production environment.

Prerequisites and Dependencies

This cumulative update is only compatible with K2 blackpearl (4.7). Each new cumulative update contains the updates and fixes that were included with the previous cumulative updates. The cumulative update does not require any previous cumulative updates or fixes to be installed, and no additional cumulative update is required to fully update a K2 environment. If you have installed individual code fixes included in this cumulative update, those code fixes are not changed unless a newer version of the code fix is available for the update.

Before you install this cumulative update, please check the K2 Product Releases and Build Numbers article to verify that this is the latest cumulative update available and that you have a current backup of your K2 database.
Database owner permissions are required to install this cumulative update or any of the fix packs.
