But they confirmed that they will request the old passport once new PP arrives and then cancel the old one and return both the passports back to me by mail.
Ah yes I'd only ever done in places when I could just come in but that was in the 'before times.' Makes sense they basically just do it as you say (basically by courier).
 
I'm considering doing the online passport renewal, but have one important question - I can't see from instructions whether they require you to return the old passport, and if so, will they cancel and return it to you. I have some reasons to keep it, and would like to - although in a pinch I guess I could scan it all.

Anyone had experience with this or seen an answer to this?

I'd be interested if anyone has experience they could share with this process. Now that they are offering a service guarantee of about a month, works fine for me.
Hi there, thank you for the information! Can you pls let me know if I do online passport renewal, can I save the form and edit later then submit the application? I have not done the photo yet, but kinda want to jump start to get the spot first! Thank you!
