Configure Teradata Channel-Attached Client

We went from NCR access to V2R6 Teradata(different from our in-house V2R5 on ncr4455).
Is it possible to configure Teradata Channel-Attached client to connect to V2R6 Teradata?

For example, for Network-Attached, we just update /etc/hosts file with IP (points to v2r6 database).
