permissions and shares

We need to move many folders from one NTFS partition to another NTFS partition on the same server. We need to maintain the permissions and shares for each folder/file. I believe going to a DOS prompt and using xcopy *.* destination /v /s /e /k /r /h /o /x will copy every file in the source folder while:
v - verifing each file
s - maintaining directory structure
e - including empty subdirectories
k - maintaining the read-only attribute
r - including the read-only files (see above)
h - hidden files
o - maintains NTFS permissions
x - sacl permissions.

Will this work if changing partitions? Am I missing or misunderstanding anything about xcopy?
