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,
  1. Add - Type - Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
  2. Add - Type - Path "C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
  3. $siteURL = Read - Host "Enter site Url"
  4. $listName = Read - Host "Enter List Name"
  5. $userId = Read - Host "Enter UserName"
  6. $password = Read - Host "Enter password"
  7. $credentials = New - Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userId, (ConvertTo - SecureString $password - AsPlainText - Force))
  8. try {
  9. $context = New - Object Microsoft.SharePoint.Client.ClientContext($siteURL)
  10. $context.Credentials = $credentials
  11. $oWeb = $Context.web
  12. $context.Load($oWeb)
  13. $list = $oWeb.Lists.GetByTitle($listName)
  14. $list.ListExperienceOptions = "ClassicExperience"
  15. $list.Update()
  16. $context.ExecuteQuery()
  17. } catch {}
By the below code, you can convert a classic list/library to new experiences (modern experience),
  1. try {
  2. $context = New - Object Microsoft.SharePoint.Client.ClientContext($siteURL)
  3. $context.Credentials = $credentials
  4. $oWeb = $Context.web
  5. $context.Load($oWeb)
  6. $list = $oWeb.Lists.GetByTitle($listName)
  7. $list.ListExperienceOptions = "NewExperience"
  8. $list.Update()
  9. $context.ExecuteQuery()
  10. } catch {}

  5. $credentials = New - Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($userId, (ConvertTo - SecureString $password - AsPlainText - Force))
  6. try {
  7. $context = New - Object Microsoft.SharePoint.Client.ClientContext($siteURL)
  8. $context.Credentials = $credentials
  9. $oWeb = $Context.web
  10. $context.Load($oWeb)
  11. $context.ExecuteQuery()
  12. $lists = $oWeb.Lists
  13. $context.Load($lists)
  14. $context.ExecuteQuery()
  15. foreach($list in $lists) {
  16. if ($list.ListExperienceOptions - eq "NewExperience" - and($list.Hidden - eq $false)) {
  17. $list.ListExperienceOptions = "ClassicExperience"
  18. $list.ListExperienceOptions = "ClassicExperience"
  19. $list.Update()
  20. $context.ExecuteQuery()
  21. }
  22. }
  23. } catch {
  24. sleep 5
