im running a single exchange 2010 server running all roles except edge which we don't use
I have around 2000 users.
I want to move to 2013 exchange and use kemp load balancers
I was thinking I would deploy just 2 servers with all roles installed
what is the best way to implement this without having too much impact on current 2010 mailbox
as this is my first 2013 install I don't want to break existing setup
I have read that as soon as 2013 is installed all mail routes through this
just looking a little help
