You can try to revert the convert1to2.py script, but you will encounter several difficulties. Also annotation guidelines for some constructions were underspecified in UD 1.0, so it is not possible to create a general 2to1 tool, but rather a tool specific for a given treebank.

@martinpopel thanks. I also found that there are many-to-one mappings from v1 to v2, so I guess it's impossible to make exact revert. Anyway, I've bypassed this problem.
