I don't know if this is the "best" way, but is one I've done for years . . .

cd srcdir ; tar -cf - . | (cd destdir ; tar -xpf -)
which for your example would be:
cd /FILESYSTEM; tar -cf - . | (cd /storage/FILESYSTEM ; tar -xpf -)

then you would

rm -rf /FILESYSTEM
ln -s  /storage/FILESYSTEM /FILESYSTEM
