Reverse script fails with an error



The system is upgraded from Pega Platform 7.3.1 to Pega Platform 8.2.1 using the out-of-place Upgrade process. The Reverse script fails with an error.

Error Messages

Verify ML Reversal Readiness:
This Reversal requires distribution image of 08-02-03, but found 08-02-02

Steps to Reproduce

  1. Upgrade Pega Platform 7.3.1 to Pega Platform 8.2.1
  2. Configure with PEGARULES and Reverse_timestamp.xml.
  3. Run from Pega Platform 8.2.1 installer.

Root Cause

This behavior is as per Pega product design.

For more information, refer to:


Here’s the explanation for the reported behavior:

The Reverse script must be used only to reverse patch release updates and not the full platform version updates.  That is, the user can reverse Pega Platform 8.2.1 to Pega Platform 8.2; but cannot reverse Pega Platform 8.2.1 to Pega Platform 7.3.1 using this script.

In order to reverse the upgrade to what is required, backup the database from before the upgrade. Since the user is already on a split schema and would have the rules schema intact to revert, data schema must be backed up before starting the dataOnly upgrade (if the user required a method to revert the version back for any reason).
