NOTE: When upgrading a JACE-8000 from an installed older release to
Niagara 4.8 the persistent log files under /var/slog will not be preserved. The reason is that
Niagara 4.8 contains an OS upgrade from QNX6.5 to QNX7.0 which uses a different log file format. During the upgrade the old QNX6.5 log
files are deleted and new QNX7.0 files are created.If the existing log files are needed, make a copy prior to upgrading.
