Update: everything seems to be working fine.
On windows you can't change the symlinks (called junctions on windows). You
have to delete them with rd symlimk_id, and then recreate them pointing to
the new location with:
mklink /J symlink_id path_to_new_location

Have to be specially carefull to recreate the symlinks correctly!

Thanks again.
