Integrated web application server changes

Support has been withdrawn for the integrated web application server (IAS) version 7.1. During the install of the IBM® i 7.2 operating system, all IAS version 7.1 server instances are automatically upgraded to IAS version 8.1. For most IAS instances this upgrade is transparent. However, if your IAS server instance no longer works correctly after the upgrade to version 8.1, please contact IBM support for assistance.

Newly created integrated web application servers will be based on IAS version 8.5, the technology used for the server is the WebSphere Application Server V8.5.5 Liberty Profile. Already deployed servers running IAS 8.1 will continue to function, although it is highly encouraged that customers transition to the new server as soon as they are able to since the old runtime will be removed in a future release. Note that there is no automatic upgrade from IAS version 8.1 to 8.5 since the runtimes are based on totally different technologies.
