Version Interoperability Between Enterprise Gateway Server and Internal Server
Prior to version 9.7, Enterprise Gateway Server and Internal Server had to be the same version of Integration Server. However, beginning with version 9.7, this requirement is removed. Enterprise Gateway Server can now operate with previous versions of Integration Servers acting as Internal Servers. For example, Enterprise Gateway Server version 9.7 can work with Integration Server versions 9.7, 9.6, and 9.5 SP1 as the Internal Servers.
Interoperability between versions of Enterprise Gateway Server and Internal Server have the following benefits:
You can upgrade only the
Integration Server acting as
Enterprise Gateway Server without having to upgrade the
Integration Server acting as the Internal Server.
You can leverage the features that are available in the latest releases of the
Enterprise Gateway Server.
Keep the following information about Enterprise Gateway Server and Internal Server version interoperability in mind:
The version of
Enterprise Gateway Server must be equal to or higher than the version of
Integration Server acting as the Internal Server.
The version of
Integration Server acting as the Internal Server must be 9.5 SP1 or later.
You must obtain the correct
webMethods Enterprise Gateway license from
Software AG for the version of
Enterprise Gateway that you want to run.
If installing
Enterprise Gateway for the first time, you must select the correct release version of
webMethods Enterprise Gateway that you want to run from the list of available releases in the
Software AG Installer regardless of the version of the
Integration Server acting as the Internal Server. For example, to install
Enterprise Gateway 9.7 you must select
webMethods 9.7 as the
Release version in
Software AG Installer.
You cannot upgrade
Enterprise Gateway using the overinstallation procedure. To upgrade
Enterprise Gateway, you must first install the
Integration Server that you want to host
Enterprise Gateway and then, install the higher version of
Enterprise Gateway in the host
Integration Server. For example, to upgrade
Enterprise Gateway 9.6 that is hosted in
Integration Server 9.6 to
Enterprise Gateway 9.7, you must first install the host
Integration Server 9.6. Then, you must run
Software AG Installer again to install
Enterprise Gateway 9.7 on the new installation of
Integration Server 9.6.
You must install
Enterprise Gateway and Internal Server in different installation directories and preferably, on different machines. Do not configure a single
Integration Server to be both an
Enterprise Gateway Server and an Internal Server.
Enterprise Gateway fixes are delivered as part of
Integration Server fixes.
If a version of Internal Server is not compatible with the
Enterprise Gateway Server that you are configuring,
Integration Server logs an error message stating the same in
Enterprise Gateway Server as well as the Internal Server.
Internal Server and
Enterprise Gateway Server must use the same type of client authentication for the external port.
Integration Server 9.5 SP1 does not support using password digest for client authentication. If your Enterprise Gateway Server is 9.6 or higher, you cannot use digest authentication if your Internal Server is version 9.5 SP1.
