Hi
500 classes is not 'very big'. The corresponding model with 500,000
objects might be.
Ideally you want a bidirectional transformation language such as QVTr,
however the main Eclipse implementations only support editing today. You
could try the Medini or ModelMorf implementations.
Alternatively you can implement two unidirectional transformations, in
which case your choices are at least
- QVTo (most standard)
- ATL (most mature)
- Xtend2 (most Java-like)
- Epsilon (most diverse)
- Viatra2 (most unknown to me)
With only 20 deviations, handcrafted Java and mapping tools may also be
options

For the ATL solution, see this thread:
