Change Page Layout using PowerShell

Hi,

We had a requirement of changing page layout through PowerShell i.e.

If certain pages are using page layout pagelayout1,need to change those pagelayout2

So through PowerShell script, I am checking if the page is utilizing pagelayout1,

If it is, then I am changing to page layout2 of that page as below

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue

#Variables for Web and Page URLs

$WebURL="siteurl"

#Get the web and page

$Web = Get-SPWeb $WebURL

#Get Publishing Site and Web

$PublishingSite = New-Object Microsoft.SharePoint.Publishing.PublishingSite($Web.Site)

$PublishingWeb = [Microsoft.SharePoint.Publishing.PublishingWeb]::GetPublishingWeb($web)

#Get Pages Library

$PublishingPages = $PublishingWeb.GetPublishingPages()

#Iterate through each page

foreach ($Page in $PublishingPages)

{

    $pageurl = $Page.url

    #Get the web and page

    $Web = Get-SPWeb $WebURL

    $File = $Web.GetFile($pageurl)

    if($File.Properties["PublishingPageLayout"].Contains("_catalogs/masterpage/pagelayout1.aspx"))

    {

    write-host "Got it"

    $File.CheckOut("Online",$null)

    $File.Properties["PublishingPageLayout"] = $WebURL+"_catalogs/masterpage/pagelayout2.aspx, Verified"

    $File.Update()

    $File.CheckIn("Page layout updated via PowerShell",[Microsoft.SharePoint.SPCheckinType]::MajorCheckIn)

    }    

    

}

$Web.Dispose()
