That's the way to do it.

However, it's important to know how the copy command works. While
globbing shouldn't be an issue, the uid could be one, depending from
were you copy, since the uid not necessarily is always 1000. IOW
it should be considered to copy with root privileges and the -p
option. I would use the -p option anyway,
"-p same as --preserve=mode,ownership,timestamps".

So the copy command after su or sudo would be

  cp -pr /path/of/old/dir/ /path/to/new/

Assumed you're using a plugin, you might need to copy additional
directories/files. I for example use bogofilter to sort out spam. The
directory to copy is ~/.bogofilter/.
