Regular patch upgrades are essential to keep your QAD ERP system secure, stable, and running with the latest features and fixes. This guide walks you through the recommended steps for performing a safe and smooth patch upgrade to minimize downtime and avoid common pitfalls.

Why Patch Upgrades Matter

Patches provide critical updates including security enhancements, bug fixes, and performance improvements. Applying these updates promptly protects your system from vulnerabilities and ensures compatibility with other integrated applications.

Pre-Upgrade Preparation

Review Release Notes
Before starting, carefully review the patch release notes available in the QAD Customer Portal. Understand the scope of changes and any specific prerequisites or post-upgrade tasks.
Backup Your Environment
Always perform a complete backup of your databases, configuration files, and customizations. This provides a safeguard to restore your system in case of unforeseen issues.
Notify Stakeholders
Inform all relevant business units and users about the scheduled upgrade window and expected downtime to manage expectations and reduce disruptions.
Test in a Sandbox Environment
Apply the patch first to a non-production sandbox or test environment. Validate critical workflows and integrations to identify potential conflicts or issues.

Step-by-Step Patch Upgrade Procedure

Suspend User Activity
Block new logins and notify users to save work and log out to avoid data corruption during the upgrade.
Apply the Patch
Follow the official QAD patch installation instructions, executing scripts and applying updates in the prescribed order.
Run Data Integrity Checks
After the patch, run automated data integrity and consistency checks to confirm the system is stable.
Restart QAD Services
Restart all relevant QAD services and middleware components to apply changes fully.
Validate System Functionality
Perform key transaction tests such as order processing, inventory updates, or financial postings to ensure the system operates as expected.

Post-Upgrade Activities

Monitor Performance
Closely monitor system performance and logs for any errors or unusual activity over the following 48 hours.
Communicate Completion
Notify users and stakeholders once the upgrade is successfully completed and normal operations resume.
Document the Process
Record upgrade details, encountered issues, and resolutions for future reference.

Troubleshooting Common Upgrade Issues

Failed Script Execution:
Review error logs, ensure permissions are correctly set, and re-run failed scripts.
Data Discrepancies Post-Upgrade:
Use built-in reconciliation tools to identify and fix inconsistencies.
Service Startup Failures:
Check system resource availability and dependencies; consult QAD Support if required.
