If you are upgrading from Content Engine version 3.5.2 on Windows, you can upgrade and continue to use Windows, or you can migrate your Content Engine to UNIX.
In either case, you must prepare the Content Engine application for deployment and then upgrade the object store data.
Migrating
your Content Engine version 3.5.2
on a Windows server to Content Engine version
5.0.0 on UNIX requires an installation of Content Engine on your UNIX machine. You
also need access to a Windows machine to install and run IBM® FileNet® Enterprise Manager and the Content Engine Upgrader tool. You do not
need access to a Windows machine to install and run Content Engine Web Upgrade Tool because
it is deployed on the same application server instance where Content Engine is deployed.
It is a best practice to retain a Windows machine where version 3.5.2 of IBM FileNet Enterprise Manager is installed. If you use the Content Engine Upgrader tool, you need access to this Windows-based tool. If you use Content Engine Web Upgrade Tool, you can browse to it only from a machine where version 8.0 of Microsoft Internet Explorer is installed.
