Recently, I ran into a project involving the migration from MVC to Headless, which required updating layouts, renderings, and placeholders. I wrote some PowerShell scripts to handle these updates efficiently.

Overview

This PowerShell script performs the following tasks:

• Updates the default layout for items in a specified content tree path.
• Removes specific placeholders from both default and mobile layouts.
• Replaces specified renderings with new ones.
• Updates placeholders based on provided mappings.

Prerequisites

Before executing the script, ensure you have the following:

• Access to the Sitecore instance with appropriate permissions
• PowerShell installed and configured to run Sitecore scripts

Parameters

• $startingPath: The root path in the content tree where the script starts processing items.
• $defaultLayoutPath: The path to the new default layout item.
• $reportOnly: If set to $True, the script will only report the changes without making any updates.
• $useFinalLayout: Determines whether to use the final layout during processing.
• $placeholderMappings: Array of placeholder mappings for old to new placeholder keys.
• $renderingMappings: Array of rendering mappings with old and new rendering IDs and names.

Feel free to modify and extend the script to suit your unique needs. Happy scripting!
