Relex 2011 does not offer a Corporate Edition. To preserve backwards compatibility, existing Corporate licenses are not changed.

When you convert prior files to Relex 2011 files, at the end of the conversion, a page displays the system administrator user name and password. It explains that you should print or save this account information as it is needed to create new databases in Windchill Risk and Reliability Administrator and to perform administrative and maintenance database tasks.

This application is no longer installed in any Edition as the PTC method is used for licensing.
