I have a small domain of 6 users looking to move to office 365 from hosted pop mail. the mail, contacts and calendar (and they really aren't using the calendar and have just a few contacts) are in the PST on their win 7 machiens running outlook 2010 or 2013 depending on the machine.
Is it as simple as
create users in office 365 control panel
change the MX record for the domain's DNS (hosted by godaddy as is the POP mail)
how long would you wait for that to propogate?
create a new exchange account in outlook / remove the POP account?
Import the old PST into the OST for the new Exchange account
