Upgrading To ownCloud 9
- 
 After upgrading to OC 9 using the CentOS 7 package manager I get this when I try to login Not Found The requested URL /owncloud/ was not found on this server. Any idea what to check now? 
- 
 my upgrade form 8.2.3 to 9.0.1 broke my system. I have not had time to troubleshoot. I just rolled it back. Sorry not to be much help 
- 
 How do you roll it back?

 This might be able to help. https://forum.owncloud.org/viewtopic.php?t=15224 
 Sorry I have not messed with ownCloud enough to know what's going on EDIT: Not even sure if Rollback is officially support or not :s 
- 
 Darn, that didnt help either. Anyone else break OC after upgrading to 9? How did you fix?

 Should I think about wiping and reinstalling CentOS and OC? What directories do I need to backup? /owncloud/config, /owncloud/data

 @alex.olynyk said: Should I think about wiping and reinstalling CentOS and OC? What directories do I need to backup? /owncloud/config, /owncloud/data No, ownCloud has an entire database structure also. Did you upgrade without a backup? That is never a good plan. There are instructions on how to backup an ownCloud install on their website. I have never used it because I do not currently have any installs hosted on a system where i have no snapshot ability.

 Took a snapshot before I upgraded but dont see the snapshot now. Guess I am having Hyper-V issues. So I am screwed.

 Will I be able to preserve the user accounts if I have to install from scratch?

 @alex.olynyk They are all in the database. Assuming you used MariaDB/MySQL then jsut back it up like any other database
