With deepest respect to drooney, the newer products (H8000,7600) should be able to read PCMCIA cards from older units, although this will not have been tested much, so there may be the the odd issue.

Note that these later units include improved versions of most of the presets in the earlier units, so there will not be many reasons to transfer them.

Sigfile should in general transfer, but there may be some incompatabilities due to changes in the modules.
