Upgrade Process

1. Complete the pre-upgrade tasks for the domain to ensure that you can successfully run the installer.
2. Upgrade the domain. To upgrade the domain, run the Informatica server installer and select the upgrade option. The domain upgrade wizard installs the server files and configures the domain. If the domain has multiple nodes, you must upgrade all nodes. When you upgrade each node in the domain, you can choose to change the node configuration to allow changes to the node host name, port numbers, or domain configuration repository database.
   The following table describes the actions that the installer performs when you upgrade the domain:

   Tasks	Description
   Runs Informatica Upgrade Advisor	Installer runs the pre-upgrade to validate the services and checks for obsolete services in the domain. Resolve the conflicts before you proceed with the upgrade.
   Installs Informatica.	Installs Informatica directories and files into the new directory.
   Copies infa_shared directory.	Copies the contents of the infa_shared directory from the existing installation directory into the new installation directory.
   If the existing domain uses the Metadata Manager Service, copies mm_files directory.	Copies the contents of the mm_files directory from the default location in the existing installation directory into the new installation directory.
   Upgrades the domain.	Upgrades the domain to run version 10.1.1 application services. The upgrade retains the user and administrator accounts in the domain.
   Starts Informatica Services.	Starts Informatica Services on the node.

3. Upgrade the application services. After you upgrade the domain, log in to the Administrator tool and upgrade the application services. The service upgrade wizard provides a list of all application services that must be upgraded. It upgrades the services based on the order required by the dependent objects.
4. Upgrade the Informatica clients. Use the client installer to upgrade the following Informatica client tools:
   • PowerCenter Client
   • Informatica Developer
     Upgrade Informatica Developer to the Informatica version, including the hotfix version, of the domain upgrade.
     You cannot connect to the Informatica domain using the Developer tool from a previous version.
   To upgrade Informatica clients, run the Informatica client installer and select the upgrade option. If the clients are installed on multiple machines, upgrade the clients on all machines.
5. Perform the post-upgrade tasks.
   If you upgrade the Informatica installation on more than one machine, complete the first upgrade with the detailed instructions in this guide. You can use the upgrade checklist in the appendix to perform subsequent upgrades.
