All installations of the Vertica ODBC driver for Mac OS X are uniquely identified by a package ID and version number. The package ID does not change between versions, but the version number does.

Therefore, multiple installations of the same version of the driver cannot coexist on a single operating system.

Upgrading—Newly installed versions of the Vertica ODBC driver for Mac OS X automatically upgrade the relevant driver system settings. Any DSNs associated with a previous version of the driver are not affected, except that they begin using the newer version of the driver.
Downgrading—Run the uninstall script to remove the current version of the Vertica ODBC driver for Mac OS X. Complete this step before installing an older driver version.
