Description:
As part of its installation process TIBCO iProcess Engine also installs a version of Apache Tomcat which is utilized by a number of
iProcess features including: Server Manager and Hawk Integration.

From time to time newer versions of Apache Tomcat are released to resolve problems that have been found. Customers may want
to take advantage of a newer version of Tomcat in preference to the one that was originally installed with iProcess Engine.

TIBCO has successfully performed the testing to update the version of Tomcat originally installed with iProcess Engine.

    1)    TIBCO iProcess Engine 11.5.0 installs Tomcat 7.0.51 as part of its installation process. TIBCO has successfully tested that
           this version can successfully be replaced by Tomcat 7.0.68 or above.
    2)    TIBCO iProcess Engine 11.6.0 installs Tomcat 8.0.30 as part of its installation process. TIBCO has successfully tested that
           this version can successfully be replaced by Tomcat 8.0.32 or above.

When updating the version of Tomcat provided with iProcess Engine the following steps should be followed:

    1.    Back up the following folders to a safe location that must be outside of the $SWDIR directory:
           a.    $SWDIR/tomcat/webapps/ipsvrmgr
           b.    $SWDIR/tomcat/webapps/webdav
    2.    Copy the new version Tomcat to $SWDIR, overwriting the existing Tomcat, and leaving the permissions and ownership as they are.
    3.    Copy ipsvrmgr back to $SWDIR/tomcat/webapps
    4.    Copy webdav back to $SWDIR/tomcat/webapps
