I am using owncloud 8.1 stable one a raspberry pi 2 with resbian in my home network with an external HDD with the user folder on it.
For some quite now I have some troubles with my contacts. I cannot create, edit or delete contacts in my owncloud.
I got the recommendation to upgrade my owncloud. But the upgrade path seems ridiculous
8.1.0 -> latest 8.1.x -> latest 8.2.x -> latest 9.0.x -> latest 9.1.x
I would prefer a clean install of the latest version.
What do I need care of before I make a clean install?
I have no shared content. I use my owncloud to sync /backup my few documents and as a Google calender and contacts replacement. So I could export my contacts, calender and todo-list as a file, make a clean install with 9.x and just import my contacts, calender and to do list again. And since my user folder is on the external HDD and don't need to care about this right?
