How to migrate shared mailbox from exchange 2016 to exchange online

Hello, we're working in an Hybrid architecture, with exchange 2016 CU18 Server and Exchange Online. I've had to migrate more than 200 mailboxes shared from on-prem to exchange on-line. How can I do to move them and keep the same permissions that the users have on prem now?
Thanks a lot.

Yes, permissions will be retained .
You may need to re-do SEND AS perms if they have any of those however.

From what I have seen, if you are using the latest version of AADConnect and Perms are set now, they will continue to work after you move the mailbox to 365.
