Hi Friend's in this article i am trying to achieve to write a script that will change MasterPageFile URL  for all Content  Pages (EditForm.aspx , NewForm.aspx & DisplayForm.aspx) on all  Particular Site Collections in a web application.

the above can be achieve both pragmatically and in power shell....u can see below image after successfully updated

the below code u will get basic idea how to change using both powershell and server object model.

Powershell script 

$spSourceWeb = Get-SPWeb "url";          # pass site url
$page = $spSourceWeb.GetFile(url)          # pass file url
$filebytes = $page.OpenBinary()
$filestring = [System.Text.Encoding]::UTF8.GetString($filebytes)
$replacedstring  = $filestring.Replace("~masterurl/default.master","site/_catalogs/masterpage/seattle.master")
$page.SaveBinary([System.Text.Encoding]::UTF8.GetBytes($replacedstring))

---------------------------------------------------------------------------------------------------------
Programatically

Dim _site As SPSite = New SPSite("URL")
Dim _web As SPWeb = _site .OpenWeb()
Dim _list  As SPList = _web .Lists("Demo")
Dim _formcollection As SPFormCollection = _list  .Forms
For Each _f As SPForm In _formcollection 

Dim _spformfile As SPFile = _ww.GetFile(_web Url + "/" + _f.Url)
Dim data As Byte() = _spformfile.OpenBinary()
Dim s As String = Encoding.UTF8.GetString(data)
Dim replaced As String = s.Replace("~masterurl/default.master", ~site/_catalogs/masterpage/seattle.master")
 _spformfile.SaveBinary(Encoding.UTF8.GetBytes(replaced))

Next
