If the DIGITAL UNIX or Tru64 UNIX system being migrated does not already include the driver used by the configured Avanti DE435 or DE500, prepare and test a release-matched kernel before cutover. Historical systems commonly require 'tu' support, but the driver name, supported adapter, and kernel procedure must be confirmed for the exact guest release. Keep a generic or previously working kernel bootable until the replacement has been verified.

These retained document identifiers are historical references, not proof that one set of steps applies to another DIGITAL UNIX or Tru64 UNIX release. Use the documentation supplied with the installed guest and verify both network operation and a fallback boot before retiring the previous kernel.
