Upgrading

Upgrading an earlier version of IBM® Cognos® TM1® to the newest version should be considered a process that you perform in stages.

You should treat upgrading as an IT project that requires careful planning, adequate time, and resources.

Upgrading from version 10.2.0

Upgrading from Cognos TM1 version 10.2.0 to version 10.2.2 requires a full manual uninstall, and then a full installation of the new version.

For more information, see Upgrading from Cognos TM1 version 10.2.0.

Upgrading from version 10.1.x

Upgrading from Cognos TM1 version 10.1 or 10.1.1 to version 10.2.2 requires a full manual uninstall, and then a full installation of the new version.

One main difference between versions 10.1.x and 10.2.x, is the required web application server for Cognos TM1 Web. Starting with version 10.2.0, Cognos TM1 Web does not use Microsoft Internet Information Services (IIS) but instead uses a Java web application server, such as the provided version of Apache Tomcat.

For more information, see Upgrading from Cognos TM1 version 10.1.x.

Upgrading from version 9.x

Upgrading from Cognos TM1 version 9.0.x, 9.1.x, or 9.5.x to version 10.2.2 requires a full manual uninstall, and then a full installation of the new version.

Note: TM1 9.0.x and 9.1.x databases are automatically converted to Unicode when they are opened (started) with a TM1 server version 9.4 or higher. Once an older TM1 database is converted to Unicode, it can no longer be opened in the earlier versions of TM1.

For more information, see Upgrading from Cognos TM1 version 9.x.
