Named
Manually updating a Dynamic controlled zone
"If you have to edit the zone files of dynamic zones manually while the DNS server is running, you'll have to freeze the zones with # rndc freeze <myzone> before editing and unfreeze them with # rndc thaw <myzone> after editing. This is because named(8) has internal state information and external journal files attached to dynamic zones that have to be kept in sync with the zone files[1]".
Rsync
To delete files in the target if they disappeared from the source, then add the --delete option to your command. For example:
rsync -avh source/ dest/ --delete
NB: -avh is for --archive --verbose --human-readable[2].
Migration of folders to a new server
