Checking for Incompatibilities between Version 21.0.6 and 21.0.7

As a system administrator, you need to check incompatibilities between consecutive versions before upgrading your system. Check the compatibility matrix to find the relevant information on supported versions, setup, or prerequisites. For more information, see Compatibility Information.

The tables below list new features that might lead to compatibility issues or should be taken care of when upgrading; they do not list all new features of this AE version. New features are described in full in the Release Highlights and Release Notes.

More information:

To provide a better overview, the tables are categorized by the severity of the issue. There are three different categories:

  • Critical: Issues that must be addressed, otherwise the system will not work
  • Behavior change: Functionality changes in existing features that might have an impact on your system
  • Advisory: Different issues you should be aware of but might not have an impact on your system

The columns display the following information:

  • Topic: Name of the general topic or new feature
  • Changed behavior: What has been changed
  • Possible incompatibilities: Impact the change may have
  • Actions/Countermeasures: What can be done to identify and/or remove possible incompatibilities

This page includes the following:

TLS Gateway selection during File Transfer between TLT/SSL and non-TLS/SSL Agents.

When initiating a File Transfer, the list of TLS Gateway instances available to the Agent takes into account the Agent's net area, thus ensuring that the File Transfer tries to use a close TLS Gateway first.

N/A

Check the net area settings of the AE and the TLS Gateway instances, see File Transfer.
SNI (Server Name Indication) activated on the JCP/REST endpoints

For increased security, the SNI is activated on the JCP/REST endpoints for incoming HTTPS requests. The requested server name (from client side) is checked and must be included in the certificate as a SAN.

Note: When using SSL Termination Proxys or Load Balancers for the REST Endpoints, please make sure that the correct hostnames are used.

If the server names are not included in the certificates as SANs, after an upgrade, the keystore entry selected might be the wrong one causing the requests through the load balancer endpoint to fail.

 Make sure that the server names are included in the certificates as SANs.
