ADCS on 2008r2 DC, remove, disable and/or migrate?

I have a 2008r2 DC with certificate services installed. I can not demote and retire it until I address the certificate server. Upon review I see it only has issued certificates to internal servers and no workstations. Certificates templates in use are Domain Controller Authentication and Directory Email Replication. I am running NPS on the server as well and have a secure wireless cert issued to local server. I am not using NPS and going to remove that service prior to dealing with the Certificate Server.  I am not overly familiar with certificate services so forgive my question if naive, but can I revoke existing certs, disable the certificate services on the 2008r2 DC server, install certificate services on 2016 DC, wait for certs to be issues from new server and then decommission the 2008r2 server? I have reviewed the migration process of certificate services to a server with the same name, but it seems that I am barely using certificate services now and would like to just start over if possible. Thanks.
