Prepare the Secure Agent for Upgrade

The Secure Agent upgrades the first time that you access the Informatica Cloud Spring 2017 release. To ensure that the Secure Agent upgrades properly, you must prepare each machine where the Secure Agent runs before the Informatica Cloud Spring 2017 upgrade.
Perform the following steps to ensure that the Secure Agent is ready for the upgrade:
  1. 1. Ensure that each Secure Agent machine has sufficient disk space available for upgrade. To calculate the free space required for upgrade, use the following formula:
    2. Minimum required free space = 2 * (size of current <Secure Agent installation directory>) + 1 GB
  2. 2. If you are using a version of the Secure Agent earlier than version 30.0, back up third-party libraries, security certificates, private patches, and configuration files that you have added to the following directory:
    3. <Secure Agent installation directory>/main/bin/rdtm
    For example, you might want to back up the Microsoft Dynamics CRM krb5.conf and login.conf files.
    Copy these files to the following directory:
    <Secure Agent installation directory>/main/bin/rdtm-extra
    Files in this location will be preserved after the upgrade and copied to the following directories:
    If you are using the Secure Agent version 30.0 or higher, files that you added to the following directory are preserved after the upgrade:
    <Secure Agent installation directory>/apps/Data_Integration_Server/ext/deploy_to_main/bin/rdtm-extra
    Note: If you use certain connectors, you might need to copy some driver files, third-party library files, or security certificates to different directories after the upgrade. For details, see the After You Upgrade chapter.
  3. 3. Ensure that no tasks run during the maintenance window. If you use Informatica Cloud to schedule tasks, you can configure a blackout period for the organization. Click Configure > Schedules > Blackout Period.
  4. 4. Close all applications and open files to avoid file lock issues, for example:
