The Validation File
The Validation File contains the information required to validate that an ISSU upgrade is possible. An
ISSU upgrade is dependent upon the current version of software on the switch and the version of software
the switch is being upgraded to. If the version of code on the switch is not ISSU compatible with the
version being upgraded, the ISSU upgrade will not be allowed and an error message similar to the one
below will be displayed:
