Multiple Version Support is a new feature that allows the coexistence of multiple driver versions on a system at the same time. The following table lists a series of ODBC Driver for Teradata installation scenarios.
| Installation Scenario | Existing | Install | Remarks |
|---|---|---|---|
| Upgrade Windows | 14.10.00.00 and greater up to 17.00 | 17.00 | Pre-14.10 releases have to be removed before installing 14.10.00.00 and later versions. |
| Upgrade UNIX-with provided setup (.setup.sh) | Native installer upgrades tdodbc1620-16.20.00.00 to tdodbc1700-17.00.00.00 | 16.20 and later | The native installer cannot upgrade from tdodbc1510 to tdodbc1700 since the package name is different. |
| Fresh Install | N/A | 17.00 | No driver already exists on the system and then 17.00 is installed. |
| Side-by-Side | 15.10.01.xx, 16.10, or 16.20 | 17.00 | 15.10.01.xx, 16.10, or 16.20 already exists on the system and then 17.00 is installed in addition to the existing drivers. Existing applications that use DSN-less connections with the driver name Teradata may connect with the 16.10 driver. If you want to connect with the 16.20 or later driver then you may have to either uninstall 16.10 and create a custom driver name or change your application to use a different connection string.
You can have 15.10.01x and/or 16.10, 16.20, 17.00 all installed side-by-side.
