are you talking about delivering new mail or about migrating/importing  
mails from dovecot?

For delivering new mail LMTP is the way to go.

Importing old mail you can use the IMAP protocol to transfer the mails.
18 Years ago we migrated from UW IMAP to Cyrus 2.3.
At that time the imapcopy from UW IMAP was much faster than imapsync.

After a short search I found different tools
- imapsync https://imapsync.lamiral.info/
- imapcopy (python) https://github.com/layfellow/imapcopy
- imapcopy (UW IMAP) not sure if this still exists or can handle  
modern SSL/TLS encryption
- Any Mailclient that can configure two ore more IMAP Accounts

But I have not tested any of the tools in ages or at all, so test  
which is best for your setup/use case

Kind regards

    Michael Menge
