Exchanging a permit type B EU/EFTA (paper to plastic)

Hi there!

Purely out of curiosity I am wondering about processing times in Vaud such as,

- how long does it take to receive an invitation to book an appointment for bio-metric enrollment

- how long does it take to hear back, i.e. to receive an invitation to get one's new permit

The context is that we're moving apartments while staying in the same town in Vaud and we've just announced ourselves to the local population office. We're going to need to exchange our old paper permits to new plastic ones.

Perhaps someone has gone through a similar process recently and could share some timelines.

Thanks!
