1. Hybrid Deployment and Remote Move Migrations - overkill for small organizations.

2. IMAP Migration - moves only emails, no calendars, no tasks etc but sometimes it can be useful.

3. Third Party Tools like: Lepide, CodeTwo and MessageOps

4. PST Export/Import.

If you don´t have a lot of mailboxes to migrate you can do it manually by exporting the PSTs and uploading them to their new Exchange Online mailboxes is probably the fastest way. Hybrid will give you the best experience, you can also use Cutover migration, but you have to disable dirsync first. Get help from below informative resources:
