The following topics provide information about tasks that you might need to perform before or after an upgrade of Data Integration Connectors. Post-upgrade tasks for previous monthly releases are also included in case you haven't performed these tasks after the previous upgrade.

Post-upgrade tasks for the April 2025 release

Perform the following tasks after your organization is upgraded to the April 2025 release.

File Processor Connector

After the upgrade, you can connect to the SFTP server using key exchange algorithms from one of the following JAR files located in the Secure Agent Installation directory:
Ensure to use key exchange algorithms that are compatible with the SFTP server. By default, the Secure Agent uses key exchange algorithms from the jsch-0.1.55.jar file to connect to the SFTP server.
To use key exchange algorithms from the jsch-0.2.17.jar file, set the UseCustomAlgorithms custom property value to 1 in the Secure Agent properties.
Before the upgrade, only the jsch-0.1.55.jar file was available. You might have replaced it with the later version of the jsch-0.1.55.jar file that contains compatible key exchange algorithms for your SFTP server and renamed it to jsch-0.1.55.jar.
After the upgrade, if you run existing or new mappings using this renamed version of the JAR file, you might encounter the following error:
[ERROR] com.jcraft.jsch.JSchAlgoNegoFailException: Algorithm negotiation fail
To run mappings successfully, perform the following steps:
  1. 1Log in to Informatica Intelligent Cloud Services.
  2. 2Select Administrator > Runtime Environments.
  3. 3On the Runtime Environments page, select the Secure Agent machine that runs the mapping.
  4. 4Click Edit.
  5. 5In the Custom Configuration Details section, select Data Integration Server as the Service and DTM as the Type.
  6. 6Add UseCustomAlgorithms in the Name field and set the value to 1.
  7. 7Click Save.
For a list of key exchange algorithms that you can use to connect to the SFTP server, see the File Processor Connector documentation.
