I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

What migration method are you going to use? Hybrid will offer you the best experience, both for the primary mailboxes and the archive ones. Other than that you can use the PST Import service: https://technet.microsoft.com/en-us/library/ms.o365.cc.ingestionhelp.aspx#BKMK_NetworkUpload

Or 3rd party tools.
