I've released on CPAN Config::Model v0.625 which features the possibility to use Augeas as a persistent storage backend. (Using Config::Augeas perl bindings)
The main changes of this release are:
1. Integrated Augeas as a persistent storage backend.
2. Improved Config::Model to handle smoothly the migration of application configuration data even in the case on incompatible changes in the configuration of the application. In other words, configuration models can be set up to move and translate data from deprecated configuration parameters to replacement configuration parameters.
If you want to use the graphical model editor to experiment with Augeas integration in Config::Model, be sure to use Config::Model::Itself v0.205.

All the best
