SMTP Relay - Can I point the 2010 CAS Array FQDN to Exchange 2016? RRS feed

  • Question

  • We are migrating from 2010 to 2016.

    There are no 2010 mailbox servers left. Only hub/cas. 

    I know that many applications are using the current CAS Array (mail.company.local) as their configured SMTP Relay end-point. Is it possible to change the IP address of the Cas Array to point it to the new relay endpoint (smtp.company.local - which points to Exchange 2016)? 

    I think it will be fine but I just want to be sure -I'm afraid that maybe if 2016 still tries to connect or proxy to 2010 in some way that clients will be impacted (popups or something?).

    I hope my explanation is a bit clear :-)

    Thanks for the help already.

    If there are no mailboxes or public folders then feel free to move that namespace to 2016.
