# ID: zfs_upgrade_001_pos
#
# DESCRIPTION:
# 	Executing 'zfs upgrade' command succeeds, it should report 
#	the current system version and list all old-version filesystems.
#	If no old-version filesystems be founded, it prints out
#	"All filesystems are formatted with the current version."
#
# STRATEGY:
# 1. Prepare a set of datasets which contain old-version and current version.
# 2. Execute 'zfs upgrade', verify return 0, and it prints out
#	the current system version and list all old-version filesystems.
# 3. Remove all old-version filesystems, then execute 'zfs upgrade' again,
#	verify return 0, and get the expected message.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-06-25)
