I've deployed many Google Apps accounts and have used imapsync a number of times to migrate accounts to Google Apps.
This time however, no matter what I try imapsync refuses to work claiming my credentials are incorrect – I've checked them time and time again and they are 100% correct.
On Ubuntu 12, built from source, my command is:
imapsync --host1 myserver.com --user1 user1@server1.com --password1 mypassword1 -ssl1 --host2 imap.gmail.com --user2 user2@googleappsdomain.com --password2 mypassword2 -ssl2 -authmech2 PLAIN
Full output from the command:
get options: [1]
PID is 21316

Host1: SERVER1 says it has CAPABILITY for AUTHENTICATE LOGIN
Host1: success login on [SERVER1] with user [USER1] auth [LOGIN]

Host2: imap.gmail.com says it has CAPABILITY for AUTHENTICATE PLAIN
Failure: error login on [imap.gmail.com] with user [USER2] auth [PLAIN]: 2 NO [AUTHENTICATIONFAILED] Invalid credentials (Failure)
I have tried -authmech2 LOGIN as well which returns:
Host2: imap.gmail.com says it has NO CAPABILITY for AUTHENTICATE LOGIN
Failure: error login on [imap.gmail.com] with user [user2@googleappsdomain.com] auth [LOGIN]: 2 NO [AUTHENTICATIONFAILED] Invalid credentials (Failure)
If anyone can shed some light on this I would greatly appreciate it.

Double check the credentials, so give it a 200% check. Follow the Janne advice of checking the credentials via a standard client like Thunderbird or Outlook or manually (see below).
Take care of quoting issues with special characters in passwords, use single quotes surrounding 'passwords' and users 'values'.
Other point, --authmech2 PLAIN or --authmech2 LOGIN are useless with Gmail now since imapsync already uses them by default. If the login works with a classical email client then it definitively means it is a character/quoting issue in the values. You can check a manual login with ncat or telnet-ssl like in this example (the client part to type is "a LOGIN ..." then "b LOGOUT"):
Also try to change the password if there are weird characters in it.
