Google to office 365
- 
 hi I m doing a migration for a client that is moving from google apps to office 365. So far so good but I ve just checked their mailboxes size and some ( about 8-10 out of 45 ) are about 35-40 Gb in size. They want to move to the mid size business not the E plan ... 
 as far as size is concerned they are aware they will need to reduce the size of the mailbox soon ( as 50Gb ) limitation.Is there anything to watch out for when migrating such a massive mailbox ? I m not sure how much time it will take or if it would be easier to do it staged ? any pointers much appreciated !! ;o)

 That's definitely going to take a while to migrate! What method are you using for the transfer? 
- 
 @scottalanmiller IMAP and a CSV ..

 For mailboxes like that, Midsize isn't an option. They'll need E3, unless they already have Office 2013 ProPlus via volume license.

 Out of interest, why is your client moving?
