Complete the pre-upgrade tasks before you start the upgrade. Run the installer on all machines that host previous versions of Informatica that you want to upgrade. In a multi-node domain, upgrade the gateway nodes before you upgrade the worker nodes. Before you perform the upgrade, verify that the Informatica domain truststore file contains only the TrustedCertEntry. You must delete all the PrivateKeyEntry entries from the file.
Verify that your machine meets the minimum system requirements to upgrade the Informatica domain.
Ensure that you have a minimum disk space of 50 GB and a RAM of 6 GB to upgrade the Informatica domain.
When you upgrade, the installer requires an additional disk space used by the existing infa_shared directory.
