How to empty a calendar

Greetings,
When I import an ics file with my old (but good) Owncloud v6.0 in a calendar, I can empty it before.
Is it possible to do the same with Owncloud 10.1.1 ?
Thanx in advance for your help.

I recommend you try it out. With docker it’s super easy to bring up a test instance:

I would recommend to go straight to the latest version, which is 10.3.2 currently.
