Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

You can start by selecting an appropriate migration method and drill down the documentation here: https://support.office.com/en-us/article/Ways-to-migrate-multiple-email-accounts-to-Office-365-0a4913fe-60fb-498f-9155-a86516418842

In general, Hybrid will be the preferred scenario, but as you havent shared any details about the environment we can only guess.
