Module Name:
upgrade2.c
Abstract:
The routines in this file are Registry Mungers for the Upgrade case of
NT 3.1 to NT 3.5.
In NT 3.1 we didn't have registry entries Version-0 Version-1 etc. nor directories.
Also Setup copies the drivers to both \0 and \1 directories
so we now have to generate Version-0 and Version-1 structures in the
registry and validate that the drivers in \1 really are version 1
and those in \0 are Version-0.
These routines only operate on the Environment that matches the CPU
that we are running on. This is because Setup doesn't upgrade drivers
for other platforms during upgrade.
Code for "Upgrading" the other CPU environments is found in upgrade.c

Routine Description:
This function upgrades drivers for our spooler's environment. It expects driver
files to have been migrated by setup to the 1 and to the 0 directories. We
will scan the registry, check if there are any driver entries around and
migrate each entry.
Arguments:
hEnvironmentsRootKey this is a handle to Print\Environments opened with
KEY_ALL_ACCESS
pszEnvironmentName this is the string describing our environment
Return Value:
VOID
