The pattern detector tool in AEM helps in upfront identification of compatibility issues in upgrading AEM version from 6.x lower versions to 6.4 or higher.
It is available as a separate package and can be installed on the source AEM instance to detect violations in upgrading to the target version.
This tool is available as an AEM package at https://www.adobeaemcloud.com/content/marketplace/marketplaceProxy.html?packagePath=/content/companies/public/adobe/packages/cq650/compatpack/pd-all-aem65
Download and install this tool in the source AEM instance that needs to be upgraded.
To run this tool simply access the Pattern Detector option under Status in AEM system console (or) directly navigate to the url http://localhost:4502/system/console/status-pattern-detector
Accessing this URL executes the tool and returns the result highlighting the suspected violations and compatibility issues in migrating to the target version.
The text and json format of the output can be downloaded by accessing the URLs
http://localhost:4502/system/console/status-pattern-detector.txt and
http://localhost:4502/system/console/status-pattern-detector.json
respectively.
This tool helps with
- Performing a pre-assessment of source repository for upgrade / migration, which provides insights for evolving the right strategy for migration
- Helps in quantifying and estimating the effort involved in the migration
