If you stay with community you can use WildFly and the Infinispan modules, the reason is that the Infinispan module integrated in WildFly does not have the full functionality - it is only used for internal caching. Infinispan will have a packed set of modules to provide the full functionality.
If you plan to switch to the EAP/JDG version I would use the 0$ developer edition for migration, in this case it is very easy to switch to the last version of EAP/JDG if you go final into production with a subscription. See this page for the subscription benefits. But if you contact Sales and pay for a smaller subscription during the 'migration' time you will have the benefit of the last patches and the full access to the Knowledgebase.
