After the summer I wanted to evaluate the new Micronaut framework and in the middle of September I made a bold decision. Migrate all 10 services to Micronaut to get a feeling for the framework!
Micronaut 1.0.0 was not yet released when I started the migration project. I think I started on 1.0.0.M4, upgraded to RC1, RC2 and sometimes I was running on latest commits on the master branch. It was a bumpy road but I managed to solve all issues (the right way, not workarounds) and move on, much thanks to the amazing Micronaut team at OCI.
