I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. 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.

Well what plan you have taken in 0365. It depends on subscription you have taken for 0365 .

First thing is subscription of Office 365 what you have like Gaurav said.
Then you can proceed to with two steps:
1) Backup Gmail account data in PST format
2) Export PST to Office 365 either manually or by using PST to Office 365 tool.

Mailbox sizes in EXO vary depending on the subscription you purchase.  If Enterprise E3 or E5, the mailbox size limit is 100 GB and the archive size is unlimited.  The others, with the exception of Enterprise F1 which requires an archive license, are 50 GB and 50 GB respectively.

However, the archive seems to be flexible (with auto-expand enabled or with a call to support).

Review this guide ...

Archiving will be dependent on you configuring retention tags and policies...

For migrating mail data, I would highly recommend BitTitan for that task.
