2013 exchange question with regards to running with exch 2007

I was wondering if I need to setup the 2 servers to coexist if the plan for the migration is as follows:
Setup the exchange 2013 server then migrate over 5 or so users from the 2007 exch server and let them test for the next 2 days to make sure all is good then migrate the rest of the users starting on Friday and have them all migrated over by the end of the day on Sunday...
So if I dont setup the coexist would this work and would the users that are migrated over to the new exch 2013 server still be able to email the users on the 2007 and vice versa?

If you don't go with a full-blown coexistence it's not a big deal, it just depends on the services you want to test.  If it is all internal outlook communication, then your users will be able to email each other without issue (so long as your connectors are configured properly).  If however, you want to test Outlook Anywhere and ActiveSync, then you will need to do a full-blown coexistence (legacy record and all).

Also, be warned that users on the Exchange 2013 server will not be able to access public folders on the 2007 server and vice versa, it truly is the one thing that Microsoft modified without considering backwards compatibility.

Yeah they will need to test all like active sync, etc. So I guess I will have to setup the coexistence.

will they be able to send emails out from the 2013 and receive in (externally I mean) if the coexist is not setup?

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Yes, if you just install Exchange 2013 and don't configure anything else, then you can still put mailboxes on the Exchange 2013 server.  The mailboxes on the Exchange 2013 server will send and receive email through the connector to the existing Exchange server.

But what about outside the exchange server like gmail or any other outside email?

Warning, oversimplified example ahead:

Email directed to your external IP address still flows through the existing Exchange server.  When this Exchange server receives an email, it determines where the recipient's mailbox exists.  If the receiving Exchange server is the target, the mail is delivered directly to the recipient mailbox, otherwise, the Exchange server uses a connector to *forward* the mail to the recipients Exchange server.

As for the reverse aspect, essentially the same thing *can* happen or, depending upon your setup, you can have each Exchange server deliver it's own mail out to the internet.
