You can manually copy the config folders over the folders with the same names under /dopusdata
(There are also some under /dopuslocaldata and /dopusglobaldata but you probably don't want or need to copy those ones.)
Edit / Select Other / Select Source to Destination can help you select only the folders which already exist on the other side. (Although it's best to fully exit Opus (via File / Exit Directory Opus) and then do the copy with something else, as some config files will be overwritten on exit and/or only read when the program starts.)
