While manually migrating to Office 365, there will always be some limitations, such as:

IMAP Migration: IMAP migration to Office 365 allows only for the migration of emails; other items such as contacts, calendars, and documents are not included. There is also a limit of 50,000 items that can be moved from a mailbox, with each email being limited to 35 MB in size.

Cutover Migration: You can migrate 2000 mailboxes to Office 365 using the cutover migration method. In addition, a domain changeover will be required right away. However, until the DNS records are completely changed, there is a risk of data loss.

Staged Migration: You can only migrate the user mailbox using the staged migration method. Distribution groups, mail-enabled contacts, and distribution groups cannot be migrated. Furthermore, the inability to migrate out of Office messages as well as user mailboxes is a limitation.
