Domain update stages

Updates include multiple stages. Each stage includes specific tasks that need to be completed successfully before the next stage begins. You can view the progress of the update from the Update Tracker. After the update is applied, the domain starts and services return to the state they were in prior to update. You can view the update history of a domain from the View Update Details page.
Note: If you deregister a domain, all update history and update plans of the domain get deleted. If you register the domain again, you can't view previous update history or plans that were created before deregistration.
The following table lists the stages that the update job includes:
Stage
Description
Prepare for update
The Domain Management Service connects to the on-premises domain, downloads installer binaries and packages for the update to the Secure Agent machine, and updates third-party binaries. The Secure Agent then downloads the files to each node in the domain. The installer files are downloaded to the following location on each node: <CDI-PC installation directory>/Informatica/platform/sys/data/downloads/<update version number>/
The installer files get extracted to the following location on each node: <CDI-PC installation directory>/Informatica/platform/sys/data/installer
Prepare in Progress
The domain preparation process is currently underway. During this time, changes are being applied, but the update has not yet occurred.
Prepare Unsuccessful
The domain preparation process encountered an issue and did not complete successfully. The domain remains functional, and you may need to troubleshoot the problem or attempt preparation again before proceeding with the update.
Prepare Successful
Confirms that the domain preparation completed successfully without errors. The domain is now ready for the final update step, which can be scheduled at your convenience.
Begin update
The service process connects to the on-premises domain to start the update. For multi-node domains, the domain is shut down.
Updating
Performs update tasks including domain shutdown for single node domains, backup of domain binaries, update application, and domain startup. The domain binaries are backed up to the following location: <CDI-PC installation directory>/Informatica/platform/sys/data/backup
The backup includes only the domain binaries that are modified during the update.
Clean-up
Deletes temporary files created during each stage of the update.
Finalize
The service process that performs the update is stopped.
Note: Do not edit or delete files in the following location: <CDI-PC installation directory>/Informatica/platform/sys/data
An update requires additional disk space on the node. In the preparation stage, the job verifies that the node has a minimum of 30 GB disk space available. If not available, it generates an error and the update fails.
If the update fails at any stage, check the log messages to find the cause of the failure. You can troubleshoot and then restart the update.
