Updates to the Migration Tool

The Migration Toolkit has been updated with bug fixes and feature enhancements. Review these updates before you use the migration tool.

What's New and Resolved Issues in Version 4.13

Updated January 9, 2026

  • In custom migration scenarios, an issue was resolved where the transplant-vens-status command failed to generate CSV output on Windows systems. The tool now correctly creates CSV files on Windows environments.

  • Previously, rules that contained unmanaged workloads without hostnames were pruned or dropped from rulesets during policy sync from on-prem to SaaS. The migration sync tool now correctly handles unmanaged workload references, ensuring that valid rules are preserved and not dropped.

What's New in Version 4.12

Review these updates in version 4.12 of the migration tool.

Custom Migration CLI Updates
  • The Migration Toolkit version 4.12 includes command-line updates to: pcemigrate transplant- vens-status

  • The command used to check the VEN transplant status is updated. The --csv_output_file option is replaced with --csv_output_file_dir.

Note

This applies to both the standard and custom migrations.

pcemigrate sync – Draft policy objects
  • pcemigrate sync no longer supports syncing draft versions of policy objects.

  • Draft policy objects must be either provisioned or deleted before you run the pcemigrate sync.

Note

This applies to both the standard and custom migrations.

What's New in Version 4.11

Published: November 26, 2025

This version includes support for large-scale (greater than 20,000 workloads) migrations.

  • Added tooling enhancements and workflows to support custom migration for large customers.

  • Introduced VEN transplant capabilities using pcemigrate, which enables bulk VEN migration without requiring venmigrate.
