Can I possibly upgrade directly from 10.0.1 to 15 ? And what should I take care of?

Nextcloud version : 10.0.1
Operating system and version: Ubuntu 16.04.6 LTS
Apache or nginx version: Apache 2.4.38
PHP version : 5.6

Hello, given the above configuration, I want to upgrade my Nextcloud to a more recent version.
(mainly because i want to upgrade my PHP to 7.1 or even 7.2)

So here’s a bunch of questions :

  • Can I proceed to a manual upgrade from 10.0.1 to 15.0.4 directly or should I upgrade to intermediate versions first (and if so, which) ?
  • Apart from upgrading my PHP to 7.1 is there anything I should look for before proceeding ?
  • Is PHP 7.1 enough or should I go directly to 7.2 ? (this is a consideration because I have other things running on the server that might not break in 7.1 but might in 7.2, so i’d need to take care of that before).

If there are docs detailing answers to these questions I apologize, but i’ve not found them readily, and i’d happily consult them :slight_smile:

You should go through all major versions, best is to take the latest minor version of each.

10.0.1 -> 10.0.6 -> 11.0.8 -> …, you get all the versions here:

Regarding php, be careful since not all NC versions support all php versions. You can find the support in the documentation:

@tflidd : Thanks. I’d hope avoiding the step by step, but I suppose it’s the safest path there.
Thanks for answering though.
