Change List/Library To New/Modern Experiences Using PowerShell

In this blog, we are going to discuss how to convert the List/Library to the classic version on the Communication site.

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.

If you want to convert a classic list/library to Modern then choose “New Experience “in the “List Experience” Section.

 

 

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

 

Follow the below code to convert all the Modern list/library of a site collection to classic experiences.

$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)
    $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”.
