No. You cannot push or pull between darcs-2 format repos and darcs-1 or
hashed format repos. This might not be optimal but is understandable, since
the theory underlying the darcs-2 repository format is different.
The more important problem is that conversion to darcs-2 format doesn't
support multiple branches at all. Some people recommend the use of tailor
for this. However, on some of our repositories this fails to produce
correct results, or crashes somewhere during the conversion. I have tried
it and it is an endless frustration.
BTW, this is a point where projects (such as darcs) cannot be careful
enough: migration paths simply /must/ exists. This should have been top
priority and a milestone for the release of darcs-2.0. As it is, I have
asked twice on the darcs-users list how to convert multible branches before
I even got a single reply. I had the impression the remaining developers
are feeling almost as helpless as me.

Yes, darcs-hashed can be used together with darcs-1 repos. This works fine,
