How to modernize a classic site other than team site on SharePoint online

Question

Hi,

I have couple of site collections on my tenant which are created based on different classic templates like Document center, eDiscovery Center, Blank Site, Project Web App Site, Publishing Site , Project Site etc.

we have a requirement to convert all these sites to modern sites. For Teams classic site there is a powershell script to update a site to modern site but for any other template I could not find any Powershell script like that. I want to avoid recreation of these sites as modern site followed by Content migration.

Please let me know if there is a way to update all the non -Teams sites mentioned above to modern site.

Hi @rameez hasan ,

It is not supported to convert the entire classic site to modern site.
But you could convert classic page to modern page using PowerShell.

Convert a Classic Page to Modern Page:

$SiteURL=https://xxx.sharepoint.com/sites/xxx  
$ClassicPageName = "home.aspx"  
  
#Connect to Site  
Connect-PnPOnline $SiteURL -Interactive  
  
#Convert Classic page to Modern page  
ConvertTo-PnPPage -Identity $ClassicPageName -AddPageAcceptBanner  

Convert All Classic Pages to Modern Page:

#Set Parameters  
$SiteURL=https://xxx.sharepoint.com/sites/xxx  
  
#Connect to Site  
Connect-PnPOnline $SiteURL -Credentials (Get-Credential)  #-Interactive  
  
#Get All Pages from "Site Pager" Library  
$Pages = Get-PnPListItem -List SitePages -PageSize 500  
  
ForEach($Page in $Pages)  
{   
    #Get the page name  
    $PageName = $Page.FieldValues.FileLeafRef  
    Write-host "Converting Page:"$PageName  
  
    #Check if the page is classic  
    If($Page.FieldValues["ClientSideApplicationId"] -eq "b6917cb1-93a0-4b97-a84d-7cf49975d4ec")   
    {  
        Write-host "`tPage is already Modern:"$PageName -f Yellow   
    }  
    Else  
    {  
        #Conver the classic page to modern page  
        ConvertTo-PnPPage -Identity $PageName -Overwrite -TakeSourcePageName -AddPageAcceptBanner  
        Write-host "`tPage Converted to Modern!" -f Green       
    }  
}  

Note: Don’t forget to replace the parameters with your own.
