# ID: zfs_upgrade_004_pos
#
# DESCRIPTION:
# 	Executing 'zfs upgrade -r [-V version] filesystem' command succeeds,
#	it upgrade filesystem recursively to specific or current version.
#
# STRATEGY:
# 1. Prepare a set of datasets which contain old-version and current version.
# 2. Execute 'zfs upgrade -r [-V version] filesystem', verify return 0, 
# 3. Verify the filesystem be updated recursively as expected.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2007-06-25)
