After any upgrade, DB replication will continue as it currently exists. However, in an effort to prep for that upgrade, I would very much recommend having a look at the DB Schema Change Library tool on the support site
here. It allows you to look at any DB changes from version to version (you insert the release you're currently running and the release you're interested in moving to, and it will spit out the differences in those DB objects).
This should allow your DB team an opportunity to prep for any necessary changes in your replication processes.
