Error on JTSData import during 2.x to 3.0 upgrade

I'm attempting an upgrade from 2.x to 3.0. When I run this command:

repotools-jts -migration_importJTSData fromFile=jtsData.tar
createMappingFile=rtc-mapping.txt createTables

I get this error:

CRJAZ1778I This server is configured as an application.
CRJAZ1365I The server is attempting to connect to the following database:

currently set to 'conf/jts/indices/workitemindex'
CRJAZ1812E This command can only run on a Jazz Team Server, and is not
intended to run on applications. See the migration documentation for the
steps to run migration.

Does anyone know what the problem is?
