The upgrade process from Drupal 7 to Backdrop CMS is a refactoring rather than a rewrite but can still have challenges. It can, however be a cost-effective solution for an organization happy with their existing website and platform.
My favorite module is not available, how would I try to port it? There is actually a contributed module that can help.
How do I rethink my theme? Backdrop uses layouts that aren't part of themes. How does that work? We will go over an example of recreating a Drupal theme in Backdrop, without porting the theme using core and contributed modules.
How long will the upgrade process take?
