When planning a migration from Exchange 2003 or Exchange 2007 to Exchange Online, think about how quickly you want to migrate along with how many mailboxes you need to migrate.
If you plan to migrate fewer than 2,000 mailboxes over a weekend, or maybe even over just a few days, a Cutover migration is an option. That said, although Cutover migrations technically support the migration of up to 2,000 mailboxes, the amount of time that takes to create and migrate 2,000 users makes it more reasonable to keep Cutover migrations to 150 users or less.
If you plan to migrate more slowly, or if you have more than 150 mailboxes to migrate, you should consider a Staged migration instead.
When planning a migration from Exchange 2010, Exchange 2013, or Exchange Server 2016, you have a few more choices than you would if you were migrating from 2003 or 2007. Although the Cutover option is available to you, this method should really only be considered if you need to migrate fewer than 150 users over a short period of time, say a weekend or a few days.
An alternative to a Cutover migration would be an Express migration. For migrations of more than 150 users and for migrations that would be done more slowly, the Exchange Hybrid migration strategy should be used. All migrations for Exchange 2000 and earlier require you to use the IMAP migration option. Likewise, if you plan to migrate from a non-Exchange email system, such as Gmail, you should also use the IMAP migration option.
So, as you can see, there are quite a few options available when planning an Exchange migration to Office 365 but there is also lots of information to digest and understand before determining which migration option is best. With that said, be sure you have a full understanding of the on-prem environment before considering a migration strategy.
