Yes, the document creation, tagging, and preparation steps are completely unaffected by EDGAR Next.  The impact of EDGAR Next occurs only in the Test and Live Filing steps, where you will be offered the ability to submit filings as usual (with a password) until September 15, 2025, or provide your EDGAR Next token or tokens after March 24, 2025, depending on your preferences and delegation status.  You will need to perform the EDGAR Next enrollment process prior to using the EDGAR Next filing option, but this will not prevent you from also going back to the traditional method until 10:00 PM Eastern on September 12, 2025.
