This guide covers upgrading a 3.5 Spree application, to a 3.6 application.

Update Gemfile

gem 'spree', '~> 3.6.1'

Update your Rails version to 5.2

Migrate to ActiveStorage (optional)

Please follow the official paperclip guide if you want to use ActiveStorage instead of paperclip.

You cann still use paperclip for attachment management by setting SPREE_USE_PAPERCLIP environment variable to true, but keep in mind that paperclip is DEPRECATED and we will remove paperclip support in Spree 4.0.
