Powershell script to update personalization rule

Question

I want to update the personalization rule for all the pages which have one common rendering.

Is it possible to identify the rendering using Powershell and update the personalization rule to the target page and subpages?

Thank you.

Below is the PowerShell script to achieve it :

Import-Module -Name SitecorePowerShellExtensions

$rootPath = "sitecore/content/Home"

$renderingName = "YourRenderingName"

$newPersonalizationRule = "<rule>Your personalization rule here</rule>"

function Update-PersonalizationRule {
    param(
        [Parameter(Mandatory=$true)]
        [string]$itemPath
    )

    $item = Get-Item -Path $itemPath
    if ($item -ne $null) {
        $renderingsField = [Sitecore.Layouts.RenderingReference[]]$item["__Renderings"]
        
        foreach ($rendering in $renderingsField) {
            if ($rendering.RenderingItemPath -eq $renderingName) {
                $rendering.Rules = $newPersonalizationRule
                $item.Editing.BeginEdit()
                $item["__Renderings"] = $renderingsField
                $item.Editing.EndEdit()
                Write-Output "Updated personalization rule for item: $itemPath"
            }
        }
    }
}

function Process-Items {
    param(
        [Parameter(Mandatory=$true)]
        [string]$parentPath
    )

    $items = Get-ChildItem -Path $parentPath -Recurse

    foreach ($item in $items) {
        Update-PersonalizationRule -itemPath $item.ItemPath
    }
}

Process-Items -parentPath $rootPath

Set $rootPath to the root of the content tree where you want to start the search.

Set $renderingName to the name or ID of the rendering you are looking for.

Define $newPersonalizationRule with the XML or string representation of the new personalization rule you want to apply.
