Installing on a shared drive is also supported. Installing in one location and then moving the files to a shared location is not supported; the installation has to be done on the shared drive. In this case, the .env files located in <prefix>/teradata/client/17.20/etc folder should be used by clients to access the release. <prefix> is provided during install and the default is "/opt". See Third-Party .ENV Files for a description of the .env files.
