If the Informatica services are installed on a machine with an operating system that is no longer supported, you must migrate the installation to a different machine before you upgrade the domain.
For example, effective in 9.6.0, Informatica dropped support for 32-bit Linux. If any node in a 9.5.1 domain is on 32-bit Linux, you must migrate the node to a machine with a supported operating system before upgrading the node to 10.1.
Before you upgrade the domain, complete the following steps on the machine where you want the new version of Informatica to run:
Copy the installation directory.
Verify port requirements.
Create a system user account.
If you plan to run the Data Integration Service, PowerCenter Repository Service, or PowerCenter Integration Service on the new machine, configure native connectivity on the new machine so that these services can connect to databases.
When you upgrade the migrated node, select the
Allow changes to the node host name and port number
option. When you select this option, you can update the configuration of the node on the new machine. When you upgrade other nodes in the domain that you did not migrate to different machines, clear the
Allow changes to the node host name and port number
