===Upgrading ownCloud 8.2.1 to Nextcloud 10.x on Amahi===
About June 1, 2016 one of the founders, some developers, and some staff broke away from the ownCloud organization. The result was the creation of a "fork" product based on ownCloud 9, called "Nextcloud". Nextcloud 9 was introduced as a "plug-in" replacement for ownCloud 9. However, due to severe bugs inherited from ownCloud the update/upgrade process did not function correctly. Later releases of Nextcloud 9.0.54 and 10.0.1 repaired the process. Unfortunately due to the broken process many Amahi users stayed with one of the earliest stable releases ownCloud. Implementing Nextcloud would have resulted in users starting from scratch with new installations. This was a big problem for instances that had big collections of stored data and sharing configurations.
The supported upgrade path should be say; ''ownCloud 8.2.1 => Nextcloud 9.0.54, Nextcloud 10.0.1''. This works flawlessly. Amahi has decided to go straight to Nextcloud 10.0.1. So the question, can we skip a major upgrade step (Nextcloud 9.0.54)? Well, kind of, with some issues, it is possible. This section will help you do that. But it is '''not guaranteed''' to work for every new upgrade instance of Nextcloud 10. ownCloud 8.2.1 is the earliest release tested. If the following steps do not work for a new upgrade instance you will have to start with a totally new installation. Also, the Nextcloud Community will not help with issues the miss an upgrade step.
