I have a sub-site in SharePoint Online with a document library containing large numbers of items. I want to rename the URL of the site. I tried multiple ways including site settings & PowerShell but getting error
The attempted operation is prohibited because it exceeds the list view threshold enforced by the administrator.
$Web.ServerRelativeUrl = $NewURL in PowerShell but get same error. Also I cannot migrate the document library to new location or delete items.
Can someone suggest any working solution?
