Complete Upgrade Tasks

If you upgraded the Informatica platform, you need to perform some additional tasks within the Informatica domain.

Based on the version that you upgraded from, perform the following tasks:

Configure the JDK home directory.: To run Sqoop mappings or process a Java transformation on the Spark engine, you must configure the JDK Home Directory in the Data Integration Service properties.
Configure the Hadoop connection.: The Hadoop connection contains additional properties. You need to manually update it to include customized configuration in the hadoopEnv.properties file from previous versions.
Replace connections.: If you chose the option to create connections when you ran the
Cluster Configuration
wizard, you need to replace connections in mappings with the new connections.
Complete connection upgrades.: If you did not create connections when you created the cluster configuration, you need to update the connections. The tasks to complete connection upgrade depends on the Informatica version that you upgraded.
