I executed update.sh and it has been running for a long time without any errors or updates to the log file. How long should this take?

Here’s the end of the log file.

@JohnP695 Upgrading Pega from version 8.8 to 24.2 is a major process that can take several hours, depending on your system’s hardware, database size, and any customizations. If your update.sh script has been running for a long time without new log updates, first check if your server is still actively using CPU and disk resources, which would indicate ongoing progress. Also, review the entire log file for any hidden errors or issues that might not be immediately visible. Ensure that your database is accessible and performing well, as connectivity problems can slow down the update. If after several hours there’s still no progress, you might need to safely stop the script, make sure you have recent backups, and then try running the update again. Verify that all prerequisites for Pega 24.2 are met and consult Pega’s official upgrade documentation to ensure you haven’t missed any steps. If the problem continues, it’s best to contact Pega Support for assistance. Always perform upgrades during low-traffic periods and keep thorough backups to prevent data loss and minimize disruptions.

@SairohithThe update process was hung but after opening a ticket with Pega Support I found the problem was with my ojdbc8 driver. After downloading the latest release the update process completed without any errors.

@JohnP695 Agree. we also faced the same issue and we used the latest ojdbc8.jar and upgrade scripts ran successfully.
