I did not understand until after migration I need to keep exchange server locally to manage parts of the office 365 mailboxes but ok with that. My issue is Exchange 2010 is running on windows 2008 which needs to be removed soon. Once I get all the email removed from the user's mailboxes I thought it might be best to bring up a 2013 or 2016 Exchange server with a basic config on Windows 2012 R2 and migrate the email accounts to it. then I can work on removing the 2010 server
Does this sound correct and hate to do it but I do not like OS that cannot be updated?
