Exchange 2010 to 2013
Hi Guys,
We are having a major issue:
1) I have installed exchange 2013, as per the migration guide and moving mailboxes slowly across from the old exchange server to the new one.
2) So right now I have exchange 2010 and 2013 both running, with some mailboxes in one and some in other.
3) out DNS records point to both the exchange server: exchange.domain.xxx.com pointing to both the servers and autodiscovery also working.
One of the major issues I am having is losing connectivity to the exchange for some users internally who have the mailbox in the new server. I need to flush DNS every time to get it connected and also I have added an autodiscover entry in the host file of the machine to point to the new IP of the new exchange server. Can somone help?
Regards,

all client access has to go throug h Exchange 2013 which redirects to Exchange 2010 !
To elaborate, exchange 2013 can redirect for Exhcange 2010 mailboxes, but not vice versa.
Make sure you have identical IIS authentication for EWS, ECP, RPC and OWA virtual directory on both servers.

you must set autodiscover record to exchange 2013 only
Also mail.domain.com also should point to exchange 2013 only
Then exchange 2013 will either redirect or proxy to exchange 2010 whenever he found mailbox on exchange 2010 server
If you set external URL property on exchange 2010 virtual directories, then exch 2013 will redirect to exchange 2010
If you keep exch 2010 virtual directory external URLs blank, exchange 2013 will proxies the connection silently to 2010

Hi Guys,
Changing the autodiscover to point to exchange 2013, had created more issues, so I had to roll back. Right now, the autodiscover is pointing to both the new and the old.
Authentication is also identical. When I changed the DNS to for autodiscover to point to new server, all users who are still on the 2010 exchange, had their outlook playing up.

User may get prompt that "Microsoft outlook has made changes and you need to restart the outlook" after you pointed outlook to exchange 2013.
This is normal and autodiscover should point to 2013 only, because 2013 autodiscover record can get you 2010 mailbox but 2010 autodiscover entry won't get you mailbox on 2013 server

We had changed the autodiscover DNS settings and in the interim used the custom host file on some machines.
