Change List/Library To New/Modern Experiences Using PowerShell

Introduction

In this blog, we are going to discuss how to convert the List/Library to the classic version on the Communication site. We can convert it manually or programmatically using PowerShell.

First, we are converting the Modern list/library to the classic experience of a site collection and then we will see how to covert the classic list/library of modern experiences. We can do this through the manual method as well as in the coding (PowerShell) method.

Convert A list/library of a site collection to Classic or New experiences

By using the below code, you can convert a modern list/library to classic experiences,

Add - Type - Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add - Type - Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
$siteURL = Read - Host "Enter site Url"
$listName = Read - Host "Enter List Name"
$userId = Read - Host "Enter UserName"
$password = Read - Host "Enter password"
$credentials = New - Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userId, (ConvertTo - SecureString $password - AsPlainText - Force))
try {
$context = New - Object Microsoft.SharePoint.Client.ClientContext($siteURL)
$context.Credentials = $credentials
$oWeb = $Context.web
$context.Load($oWeb)
$list = $oWeb.Lists.GetByTitle($listName)
$list.ListExperienceOptions = "ClassicExperience"
$list.Update()
$context.ExecuteQuery()
} catch {}

By the below code, you can convert a classic list/library to new experiences (modern experience),

try {
$context = New - Object Microsoft.SharePoint.Client.ClientContext($siteURL)
$context.Credentials = $credentials
$oWeb = $Context.web
$context.Load($oWeb)
$list = $oWeb.Lists.GetByTitle($listName)
$list.ListExperienceOptions = "NewExperience"
$list.Update()
$context.ExecuteQuery()
} catch {}

Note

You also can do it manually by following the below steps to convert a library to classic experiences,

Go to List/Library Settings by clicking the gear menu of that, SharePoint page>> Click on “Advanced Settings”.
Scroll down, then from the “ListExperience” section, select “Classic Experience.

$userId = Read - Host "Enter UserName"
$password = Read - Host "Enter password"
$credentials = New - Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userId, (ConvertTo - SecureString $password - AsPlainText - Force))
try {
$context = New - Object Microsoft.SharePoint.Client.ClientContext($siteURL)
$context.Credentials = $credentials
$oWeb = $Context.web
$context.Load($oWeb)
$context.ExecuteQuery()
$lists = $oWeb.Lists
$context.Load($lists)
$context.ExecuteQuery()
foreach($list in $lists) {
if ($list.ListExperienceOptions - eq "NewExperience" - and($list.Hidden - eq $false)) {
$list.ListExperienceOptions = "ClassicExperience"
$list.ListExperienceOptions = "ClassicExperience"
$list.Update()
$context.ExecuteQuery()
}
}
} catch {
sleep 5
}

Note

If you want to convert a classic list/library to Modern, then in the coding of “$list. ListExperienceOptions ="ClassicExperience"” change the ListExperienceOptions “ClaasicExperience” to “NewExperience”.
