[REQ] Does changing the principaluri of a calendar has any impact on subscriptions?

Hi there,
I figured out that I can change the principaluri in “oc_calendars” to assign a calendar to an other account thanks to this post.

But what happens if the calendars uri (in “oc_calendars” is “personal”, which is the required default for the first calendar of each account (afaik).

And, what happens to anyone who subscribed to this calendar? Do they just see a different owner at next refresh? And do get the data as usual?

Can I not just assign the subscription URL to an other calendar? And if so, where?

I‘d transfer the ownership with occ:

I wasn‘t aware that that is possible when I wrote the other post (or maybe it even wasn’t possible back then).
