Convert MM to XMIND

mm to xmind conversion essentially represents a transformation of FreeMind mindmaps (.mm) to Xmind format (.xmind). The most obvious choice for this conversion is of course XMind itself (Pro version) and it is likely the only one as well.

But perhaps some other viable brainstorming or mindmapping software with broad support of mindmap formats exist and can be of help for mm to xmind conversion.
