Change default calendar URL to restore old caldendar

My old owncloud just went south and unfortunately the new owncloud version which I installed on my pi (10.2.0) has changed the default URL for calendars.
As my devices still got all data stored I just would like to setup my new owncloud with the same parameters (server ip, caldendar name, password, etc.) so that my device will just sync everything back on my cloud. But therefore I need to change

/owncloud/remote.php/dav/calendars/

to

/owncloud/remote.php/caldav/calendars/

Is there a way to do that?

Thanks
