I?ve done A LOT of this, and in my experience there is no easy way to do it ?
although I was working with VERY complex files.
The DTP Tools product didn?t work for me, but again ? the complexity of the
files may have been too much for their product.
Didn?t try MIF2Go, so can?t comment on that.
Had my best luck doing a lot of preprocessing on the FM file so that
conditional text, etc, could be identified later on, then exported as RTF, then
did a bunch of post processing in InDesign. Not hard, just time consuming.
Let me know if you?d like more info.
Best wishes,
