Please consult the Upgrade documentation at:

There are specific mentions therein as to changes in the configuration 

Also, please see the man page for the cyr_info(8) tool, which offers a 
lint option:

    *cyr_info*  /conf-lint/

        Lint the configuration for unrecognized settings.

    duplicate_mailbox_mode: uniqueid
    archivepartition-default: /var/spool/cyrus/spool-archive
    user_folder_limit: 5000

An example of changes you'll find are the various autocreate settings.  
Many of these were only in vendor patches in earlier versions, but are 
now standardized.  See the man page for imapd.conf(5):

For example:

    |autocreateinboxfolders:| <none>

        Deprecated in favor of /autocreate_inbox_folders/.

    |autocreatequota:| 0

        Deprecated in favor of /autocreate_quota/.

    |autocreatequotamsg:| -1

        Deprecated in favor of /autocreate_quota_messages/.

    |autosievefolders:| <none>

        Deprecated in favor of /autocreate_sieve_folders/.

A search for "Deprecated" in that man page should prove instructive.
