Google apps migration from exchange
I'm trying to sort out a migration of our exchange server over to google apps for education and I'm unsure how to proceed.
Currently, I've had Google Apps setup for our school for years but not many have bothered to take it up. This year, due to our Exchange servers age and low disk space, I'm going to migrate it over but not sure how this will affect the end user. I've configured the Google Apps directory sync for all my users so that is sussed. Google Apps password sync is still a bit of a problem due to a network error when connecting for authorization but I think that will be cleared up when we switch off our ISA in favor of a UTM in a couple weeks. So it comes down to Exchange now.
I've tried doing a mail migration with the tool provided by google but it always fails when trying to verify the .csv of users to migrate. I'm guessing I am missing some information about what is acceptable and what isn't. Would anyone have a better example or more knowledge of the parameters/fields? As far as I know it should just have email@example.com, no first name or surname etc. so it would look like this:
And once that is done, how has everyone converted their email clients to Apps from Exchange? I'm not sure if there is a GPO I can use to redirect the Outlook clients to google's servers or if I need to use the migration tool (https://tools.google.com/dlpage/outlookmigration) on each machine/account. (Btw, the tool doesn't cover Office 2013 yet which was what I was going to upgrade to since I was having to do all this work anyway. Having second thoughts about it now and may just upgrade to office 2010.)
Any help/suggestions are appreciated.
