Generally speaking this has been the case but our team recently upgraded to 9.5 and it appears Harvest is broken for the upgraded clusters. We are OCUM 188.8.131.52 and a custom build of Harvest on RedHat 7. Not exactly sure what version we are on. I will need to check the files. I will try the old method of copying and renaming the template file. It could be the collection managers. Still investigating.
After we upgraded to 9.5 our Harvest views for our 8020 also broke. Just doing a patch didn't break it, so for instance if I went from 9.4P1 to 9.4P5 it still worked. Going from 9.4 to 9.5 it broke.
Copying and renaming config file from cdot-9.4.0.conf to cdot-9.5.0.conf will get you working again. At least it did for me. Make sure to adjust ownership and permissions. Depending on your installation your directory location could be different. This is my path, /opt/netapp-harvest/template/default/.
