How to use this matrix

Use this matrix to determine what products and versions of products are supported and compatible with various versions of K2. A check mark means that the listed product/version is supported by K2. If any product or version is not listed and not covered by the Nintex Automation On-Premises Product Support and Release Strategy , it is not supported. A missing check mark means that the listed product/version is not supported with that specific version of K2.

Note:

Release Upgrade Compatibility
This upgrade compatibility matrix describes which versions of K2 ("Installed K2 version") can be upgraded to which later versions of K2 ("Version to be installed").
It is recommended that you upgrade to the latest version available.
If you have K2 installed with the K2 database in Azure SQL, you must upgrade to the next version of K2 versus jumping versions. For example, if you are on K2 Five (5.2) and you wish to upgrade to K2 Five (5.5), you must first upgrade to K2 Five (5.3), then to K2 Five (5.4), and finally to K2 Five (5.5).

Authentication (Identity Providers) Compatibility

This section lists which user identity providers can be used for inbound authentication with K2. For more on authentication in K2, see Authentication and Authorization in K2. K2 uses a concept called "user managers" to interact with identity providers; for more information on user managers in K2, see Introduction to User Managers in the installation and configuration guide. K2 Cloud uses OpenID Connect and can integrate with SCIM 2.0 identity providers for inbound authentication. If you have a SCIM 2.0-compliant and OpenID Connect-capable identity provider and do not see it listed in the supported identity providers below, please contact your K2 representative to have your identity provider assessed for future support.

Azure Active Directory (AAD)
  • K2 Cloud subscriptions require AAD and it is the only supported authentication mechanism for K2 cloud environments. You must have an AAD tenant before a K2 Cloud environment can be provisioned.
  • K2 Cloud subscriptions can leverage AAD or another supported Identity Provider (see details for other supported Identity Providers below).
  • Using AAD for authentication with K2 Cloud or K2 Five requires installation of the Azure Active Directory for K2 or K2 for Office 365 App. See the user guide topic Applications for more information.
  • Using AAD for authentication with K2 Cloud requires installation of the Azure Active Directory for K2 or K2 for Office 365 App.
  • Active Directory Federation Services (ADFS) is supported with AAD when ADFS is configured as described in the Microsoft article Azure AD Connect and federation. See Active Directory Federated Services (ADFS) for more information. ADFS enables using other identity providers (for example, Okta and Ping), if user UPNs from the identity provider are present in AAD via Azure AD connect. See the knowledge base article How To: Configure Okta to Log In to K2 Sites for an example.
  • K2 Cloud and K2 Five uses the Microsoft Windows Identity Foundation which means that only relying party trusts configured for the WS-FED protocol that issue SAML 1.1 or SAML 2.0 tokens are supported.
