I have a stone-age 8.1 installation and want to update to a current version.
however, update does not work anymore. I am not supposed to skip a major version, but on some point (Version 9 I think) the contact app got placed into some store, and this store does not exist anymore.
So I want to do a clean re-install and manually export / import the data.
Problem: exporting the contacts in owncloud 8.1 creates vcf files with some fields encoded as ENCODING=QUOTED-PRINTABLE
And the owncloud 10.6 contact app throws error messages when importing the .vcf, and ignores all contacts with such encodings.
Any idea how to re-import the contacts which have been exported by owncloud?
