Hello I would like to import very old exported zope file (.bbe or .zexp). ( Note: I know how to convert the zodb2 to zodb3...) Unfortunately theses file contains products which are not installed anymore now: old db adaptor,confera... and the import failed. This is not really nice. Is there a way to do the import anyway? not importing the unknown or broken objects?? Or to 'clean' the old .bbe/.zexp from thoses objects? Thanks Gilles
