Spark Edu Accounts. Change to Spark Post

Now that Adobe Spark Post is Express.adobe.com do we still have full Enteprise login access for our district?  I checked and my logins are still working through the school account portal.  Is there a document/article that explains this for us so we can better understand our Enterprise Free Edu tools?  I need to update all the guides and our Classlink integration url.  Somehow I missed that this was happening and just noticed today when I was making a sample info graphic for a teacher and it redirected me to the new online URL.

Thanks for any documents and clarification.
