Not quite sure what you're saying here, but if you ran the "sudo do-release-upgrade -d" command, then it will have upgraded your dovecot packages to the current version of Ubuntu 20. 

https://packages.ubuntu.com/search?suite=default&section=all&arch=any&keywords=dovecot-core&searchon=names

If I read that correctly, your dovecot version will have jumped from 2.2.33 to 2.3.7
What does "apt-cache policy dovecot-core" say?

Usually, during the upgrade it will ask you if you want to keep the existing configuration. Generally a good idea to do that (!) and then review the config afterwards for possible changes. Some items will be introduced, some will be depracated. 

Maybe others in this forum can comment on any major changes between 2.2.33 and 2.3.7. 

Any clues in the logs? /var/log/dovecot.log, and 'systemctl status dovecot'
