You can use the pg_dump from the linux-box to take the dump using directory-format and multiple processes, and also
multipleprocesses for the restore. 

You can also try to use a trigger-based replication (londiste, slony) to build a replication from 9.0 to 10, but i'm
notsure if those tools are available under windows.
