The Application Signature tool, which can be located in the Pega Marketplace was updated on May 14, 2026 to be able to better extract Case and Data content from Heritage Pega version 5 and Pega version 6 applications. The tool generates a .pegasign file with all of the relevant information from the Pega Heritage application. When creating your Blueprint, which will be used to reimagine your Heritage application, upload your .pegasign file as a Code Analysis Document in the supporting assets screen.
