Ascii Maya (ma) to Collada converter

Is there a converter from Maya ascii files (.ma extension) to Collada (.dae)?


P.S. Longer story : Seems like OpenCollada plugin only works for Maya 2008 onwards? We have an older version of Maya ( Maya 8 ). So, as I understand, the OpenCollada plugin won’t work for it. Hence, I am looking for a conversion utility to convert the output of that Maya (.ma or .mb) to Collada format.
