■ Introduction

  ACL Migration Checker (hereinafter "this software") is a dedicated 
  checking tool designed to verify that access control lists (ACLs) 
  are correctly transferred without discrepancies during data migration 
  on file servers and storage servers.

  It is especially powerful for verifying permission reconfigurations 
  and preventing human error in Workgroup environments where SID 
  migration is difficult, as well as in standard Active Directory 
  environments.

■ Key Features

  1. ACL Scanning and Saving
     Scans the ACL information set on files and folders in both the 
     source and destination environments, saving the data in a 
     lightweight compressed JSON.GZ format.
  2. Pre/Post Migration Comparison
     Compares the two obtained sets of ACL information to automatically 
     detect and list missing permissions, excessive privileges, and 
     account mismatches.
  3. CSV Export of Results
     The list of detected discrepancies can be exported in CSV format. 
     This is highly useful for post-migration reporting and creating 
     action lists for correcting access rights.
  4. Multilingual UI Support
     Automatically adapts to the OS language settings, providing a 
     seamless experience in both English and Japanese.

■ System Requirements

  - OS: Windows 10 / Windows 11
  - OS: Windows Server 2016 / 2019 / 2022 / 2025

  run it on any compatible PC.

  [Uninstallation]
  Just delete the entire folder. This software does not use the 
  Windows Registry.

■ How to Use

  1. Retrieve ACL Information
     Run the software to scan and save the access rights information 
     for both the migration source and destination.
  2. Load and Compare Data
     Load the saved source and destination data into the application 
     to execute the comparison process.
  3. Review Discrepancies

     mismatches) displayed on the screen.
  4. CSV Export
     Click the "Export CSV" button to save the comparison results 
     for your records.
