You can also use the cpio command in conjunction with find. This keeps the perms, time stamps, owners/group, links, etc. This option is independent of OS distro and/or version.
There is no guarantee that everything (uid/gid ownership in particular) will be preserved unless the command is run as root.

Notice the find command is using the PATH of (the 'dot' character) for its search path. You could use an absolute path in your find command but then you recreate that path in the new location as well. Not a bad thing in itself but it can be extra work if you need to restore.
Code:
The cpio options: p pass through mode
there are 3 modes; in, out, pass through
m preserve modification times
u unconditional
l link files instead of copying, when possible
d create directories as needed
v verbode
If available, pax is a much better tool for this task than cpio.
With pax:
* there's no need for a depth-first find traversal and no need to name each file explicitly. Unlike cpio which treats a directory like a regular file, pax (like tar) implicitly includes the hierarchy below a directory.
* there's no need to fuss over relative or absolute pathnames.
* most of the options required by cpio are not necessary. pax's default behavior in copy mode will preserve timestamps, use hardlinks where possible, and create directories as needed.
Code:
pax -rw oldir newdir
If the copying will be performed as root and all ownership and permissions should be preserved exactly, add -p e.
pax should be available on any UNIX system (GNU's Not UNIX ).
