Migrating Google Calendar & Contacts to WebDAV (CalDAV & CardDAV)

[vprasad84]

Hi,

We would like to migrate calendar & contacts of all our Google Users to a different email server which support WebDav (CalDav for calendar & CardDav for contacts)

While i see the below options, is there a way where we can use google service account & impersonate the user

also what could be the url for google carddav & caldav

cloudron-davsync sync
--source <url>
--source-username <username>
--source-password <password>
--destination <url>
--destination-username <username>
--destination-password <password>

@vprasad84 Which webdav system are you gonna use in Cloudron? Nextcloud? SOGo?

system are you gon

Thanks for revert.

I would be using IceWarp as Destination (CalDav/CardDav) & source will be Google
I have tested cloudron-davsync between 2 separate IceWarp Servers & observed the contacts migration is fine
For Calendar migration, Its giving the below error
Invalid response: 412 Precondition Failed

Found 2 items on source server.
Found 0 items on destination server.

I am looking to migrate calendar & contacts from google to icewarp webdav

[fbartels]

As far as I know there is no tool called:

@vprasad84 said in Migrating Google Calendar & Contacts to WebDAV (CalDAV & CardDAV):

cloudron-davsync

There is also no app on cloudron for icewarp.

Cloudron is a like a control panel form your server to install, update and backup pre defined apps.

Edit: such a tool actually exists: https://www.npmjs.com/package/cloudron-davsync?activeTab=readme

[nebulon]

The tool is a helper we have created to ease migration towards the apps we have packaged for Cloudron, I don't even know IceWarp and it was thus not tested against this. Maybe you can run the command again with:

DEBUG=* cloudron-davsync ...

to get more information on what might go wrong as I can't reproduce or test this locally.
