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.

For more information about product requirements and supported platforms, see the Product Availability Matrix on Informatica Network: https://network.informatica.com/community/informatica-network/product-availability-matrices/overview%20

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

option.
