Upgrading 8.2.1 to 10.0.7

Hello, due to an issue with the underlying OS, my OwnCloud installation was kept behind until now. so I have a (working) 8.2.1 install that I want to update to the latest (10.0.7 as of today)

Some useful data:

Operating system:
Gentoo Linux

Web server:
Apache 2.4

MySQL (MariaDB) (at first glance I see both MyISAM and InnoDB tables, don't know if they are all currently in use)

PHP version:

ownCloud version: (see ownCloud admin page)

Updated from an older ownCloud or fresh install:
Already update multiple times (maybe from 6 or earlier)

Where did you install ownCloud from:
Download tar from OwnCloud site

My question is: can I follow the upgrade instructions from 9.x to 10 present in the site, or there is some special path I have to follow?
Since the current version is very old, I can't use the built-in update feature as it doesn't find anymore the required tarball


you should upgrade to 8.2.11 and from there you can upgrade to 10.0.7.

Before any major upgrade I would always make a backup and test the upbrade on a test system.
