I had to migrate to a new server with my Nextcloud. Now I need to copy all contacts from the old instance to the new one. I exported the address books via the Web App but when importing again, some of the contacts are not imported and the error says “23 faulty contacts”?
I tried the following ideas already:
- .vcf files are UTF-8 encoded
- vCard Versions are mixed, but all are either 3.0 or 4.0
- I manually changed to BDAY format to ‘‘BDAY:YYYY-MM-DD’’
Nothing helped. Server log doesn’t give any error message. Any ideas how I can proceed from here? How can I debug the file to get all contacts really into new new instance?
Thank you for your help in advance.
