What Sparky said. Take as many cuttings as you can and you'll be drowning in young lavender plants next year. They take a few years to get to a decent size so leave the existing one in place until you're ready to replace it.
Left over plants from the cuttings make good gifts
If you're as bad at cuttings as me, expect about a 10% success rate... Also the successes are still tiny after a couple years. My weedy lavender self-seeded by next door's front path and is enormous. Theirs does get more sun though.
