Migration Exporter: Existing Implementation Does not Support Export from Early Atlas 0.8 Versions

Background

Current implementation of Migration Exporter uses Spring to instantiate objects. This works for most of Atlas v0.8 versions, except the early versions that did not have Spring integrated.

Analysis

The use of Spring in object creation imposes this restriction. Simpler approach by directly instantiating objects can help in supporting more versions.

There may be some inconsistencies in parameters passed during object creation. This needs to be considered.
