This plugin adds a WP CLI command designed for developers who restructure Advanced Custom Fields. It solves the specific problem where moving existing fields into a new repeater structure leaves all previously entered data inaccessible. The command updates the underlying post meta keys to match the new nested format, ensuring content remains intact after the field group change.

• CLI-Based Migration: Execute the data transformation via a single wp command, allowing for precise control, scripting, and integration into deployment workflows.
• Preview with Dry-Run: Use the --dry-run option to see exactly which posts and fields will be affected before making any permanent changes to the database.
• Targeted Execution: Scope the migration by post type, specific post IDs, or other standard query parameters to update only the necessary content.
• Handles Multiple Fields: Migrate several fields into the same repeater in one operation by specifying their slugs as arguments to the command.
• Requires Field Details: You must provide the repeater's slug and its internal field ID, ensuring the update targets the correct ACF structure.
