Interoperability / support for Informix with Mirth

Hello Team, My team is working on connecting " Mirth Connect 3.0.3 " to IBM Informix v12.10. As we work through the process, we would like to hear it from you experts, if you have come across with Interoperability / Support information for Informix with Mirth Connect. If Yes, can you please point us to the documentation that shall assist us in taking steps to configure the database connection. The documentation from Mirth Connect, do not list Informix under supported database, however, hints at having other databases configured under Custom Databases. Mirth Connect suggests at using JDBC connectivity to initiate the process to register a custom database, but making config changes to dbdrivers.xml file and mirth.properties file, where the JDBC class and URL are defined, respectively. It also mentions about placing the 'ifxjdbc' and 'ifxjdbcx' jar files under 'custom-lib' directory structure. Can you please your inputs / comments on the same. Thanks, Kamal
