I have 2 clients one SBS 2003 and the other is SBS 2008 , We are looking to upgrade to Server 2012/Exchange 2013, They only have 20 mailboxes each that need to be inhouse, neither uses sharepoint, What is the easiest way to get mailboxes over to new server. Other data on server is minimal and users can be setup again manually in new AD, Domain names will be the same as existing names. I have read lots about migrations but this seems to be overkill for 20 Users.
I realise that Server 2012 is also an overkill but with SBS being phased out i have no option.
Thanks in advance.
