Herbs: How should I move and overwinter this lavender?, 1 by dividedsky

I've had this little lavender in my summer garden, but I plan to have my garden somewhere else next year. I suspect that it might be an English lavender, maybe hidcote blue, but correct me if it looks like something else.

If I want to dig it up soon, would it be ok to put it in a container on my balcony in a somewhat similar lighting situation as it's already in? Or should I put it in a more permanent place? Or bring it indoors? If I've identified it correctly, Plant Files says that it can survive -15 degrees in my zone, which is much colder than it usually gets here.

Any recommendations?
