During training there wasn't too much fuss about it. As others have pointed out, going from CFM to IAE (maybe the other way too) is somewhat "uncomfortable" to look at the EW/D at first because of the EPR gauge. Starter, warm up and oil qty limitations vary, but nothing to worry about. Plus the MAN N1 sw on the overhead for manual engine starts.
Our training (on CBT) only highlighted the differences, when applicable, while describing a particular engine component. I reckon it was enough. Only a few things change and they're not particularly lengthy; they're more "annotations" than anything else, I think. So long as you mention the ones that pertain to the operation, I would reckon you're good to go
