>             Project: Ignite
>          Issue Type: Improvement
>            Reporter: Ivan Bessonov

> We need a couple of tests:
>  * Get a valid node configuration for Apache Ignite 3.0, try to run current 
> version of code on it.
>  * Same process, but instead of running a node on an old configuration, we 
> instead initialize the cluster with "obsolete" script. This scenario is not 
> really fail, but emulating Ignite version upgrade is problematic without 
> having a proper compatibility framework.
> The "old" configurations should be retrieved from the real 3.0 installation, 
> by calling corresponding REST/CLI commands.
> We should make sure that:
>  * Every named list configuration is populated with some values.
>  * Every instance of polymorphic configurations is tested. This is actually 
> not possible to achieve withing a single configuration file, which means that 
> we will have multiple tests for each scenario (probably a parameterized test).
> Obviously, these tests will be failing right now. We will have to disable 
> them and fix all the incompatibilities. This must be done before Apache 
> Ignite 3.1 release.
