When you migrate to Dynamic Server 10.0, you can install and test a database server instance with the same configuration files, environment variables, and sqlhosts information that you used for your source database server.
After successful conversion to Dynamic Server 10.0, you might want to modify configuration files and environment variables to take advantage of Dynamic Server 10.0 features. For more information, see the IBM Informix: Dynamic Server Getting Started Guide and your IBM Informix: Dynamic Server Administrator's Guide.
