You can do it now.

You might be as well taking some cuttings as insurance as well...

Make sure you get as big a root ball aspossible. Although it should be OK moving it now personally I'd leave it until late spring.

Cuttings are really easy. Take 3 inch shoot tips, remove lower leaves and any flowers. Put into sandy compost and in a plastic bag or propagator. Pot on when rooted and keep inside over winter.
