    I guess you are trying change subsite to site collection, but i guess its not possible just by changing the server relative url Nov 23, 2017 at 10:44

For SharePoint Online, we can't change the site collection URL, we can change the sub site URL using PowerShell with CSOM. The following PowerShell script for your reference:

#Configure Site URL and User
$SiteURL = "https://mydomain/sites/sitecollectionName/subsite"
$User = "[email protected]"
$Password = "Password"
$newUrl= "/sites/sitecollectionName/mysubsite"

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"

$SecurePassword = $Password | ConvertTo-SecureString -AsPlainText -Force
$creds = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($User,$SecurePassword)

$context = New-Object Microsoft.SharePoint.Client.ClientContext($SiteURL)
$context.Credentials = $creds
$web = $context.Web

$web.ServerRelativeUrl = $newUrl

    Here in question looks like he is trying to convert subsite to a site another collection. Does this server-relative URL change work for this? I guess its only for changing subsite URL respective to its site collection URL not to another site collection. Nov 23, 2017 at 9:22

    The suggested script works only if I keep the sitecollection path as part of the new url mydomain/sites/sitecollectionName/newsubsite I want to change url to mydomain/sites/subsite effectively removing the reference to SiteCollection in the path I get an exception "Invalid URL" when I run the script So looks like not possible Nov 23, 2017 at 10:27
