/var/lib/dirsrv/slapd-INST/db/changelogdb/  <===  this directory, and
its contents, are the 1.4.3 replication changelog (typically defined in
cn=changelog5,cn=config).

/var/lib/dirsrc/slapd-INST/db/userroot/replication_changelog.db <=== in
1.4.4 we moved the global replication changelog into a database file for
each backend.

If you don't see these, then there is nothing to clean up.

No, that is the retro changelog database.  There is no need to remove it.

So I suspect the downgrade to 1.4.3 screwed everything up.  So sounds
like you need to simply recreate the replication changelog (if you are
are staying on 1.4.3), please follow the instructions from this link:

https://access.redhat.com/documentation/en-us/red_hat_directory_server/10/html/administration_guide/managing_replication-configuring-replication-cmd#Configuring-Replication-Suppliers-cmd

Just to be safe, it might be a good idea to restart the server after
adding the replication changelog config entry.

HTH,
