Upgrading RT

After searching for hours, I have found some information, but not
what I was looking for…so if my question has already been answered
somewhere, please point me at it and I will apologize beforehand
for missing it.

What I am trying to do is upgrade an old RT 1.0.7 install to the
latest version (3.4.1, I believe).

I have found info on upgrading from 2 to 3 and then from 3 to
3.X versions, etc. But I have not found any info on upgrading
from version 1.0.7 to 2.

If anybody knows of a shorter upgrade path from 1.0.7 to 3.4.1,
I would cerainly appreciate any info.

Thanks for any information provided.
