I consider to upgrade from ownCloud 8.2.5 to nextCloud.
As I heard that the version 9 release of owncloud had serious problems with calendar and contacts, I’ve not upgraded so far.
Are those issues fixed in the current version of nextCloud and can I expect calendars and cardDav Contacts to work at least as good as before?
I also rely on IMAP authentication - anything to expect here?
All sync clients (owncloud clients) and external URLs (file shares, calendars, etc) are supposed to remain working as the API have not changed so far, right?
thanks a lot fpr any feedback
