If I understand the process correctly, to do an import from Geobase you 
would need to use a script 
(http://wiki.openstreetmap.org/wiki/Geobase2osm) to convert the files 
from Geobase to .osm files.

If you were to select a section of the city, do the geobase2osm 
conversion, then open the existing osm data in JOSM as one layer and the 
Geobase osm file as a second layer, you should be able to get some ideas 
about which parts of the map need attention.

I suspect that this might not be much more work than a wholesale 
delete+import anyway.  Remember that if you delete and replace a large 
area, you will most likely need to do a bunch of fixing at the borders 
of that area.
