Can we scale up from Persongroup to LargePersongroup with existing data?

[xenogew]

I would like to ask you, can i do something like migration or scale up the data from existing person group to large person group?

From the first place I use person group as planed the person might not go over the limitation but I found the growth is faster than I expected, so, now it go over the limitation of "person group" spec.

But I still want to continue implementing on existing data, and don't want to do the subscription process like - create group -> create person -> add faces to person from the start again.

How can I achieve for what I want, or is it possible?
