Upgrading when using deprecated dependencies

LA Drupal - Nov 2021

Why

Something new comes along
Maintainer goes away
- Mambo -> Joomla
- Drupal 6 -> 7 -> 8
- Drush -> Drupal Console -> Drush
- Ubercart -> Commerce
- Relation -> Field Collections -> Paragraphs

Goal

One D8 site
- Uses lightning distribution
  - Can gripe about this one another time
Need to move to D9
- FC to Paragraphs is primary blocker

No new maintainer

Options

Update code to be D9 compatible
- Become maintainer?
Move on
- Figure out migration path
  - Migrate module?
  - SQL?
  - Drush command?
  - Combination of the above??

Write a D9 compatible version of the module

Go through the code
Try and port it over
- Could put it up as a patch so others can use it
The code might also be very complex so it could take a lot of time

Write a migration

Migrate module is very nice
- Rollbacks, errors, logging all managed
Also a bit complex (yml + query + processing)
FC to Paragraphs migration module exists in beta
https://www.drupal.org/project/field_collection_to_paragraphs
- Only works with node and taxonomy terms
Demo

Initial thoughts

It does a lot
- Creates fields, settings, view modes, etc
  - Even if it won't bring over content due to field existing for different entity
- It works decently well
Initial migration has to be via the migrate gui
- Just craps out otherwise
Works with drush after initial setup and migration

Write a drush script

When in a bind
Write all the niceties that migrate provides
- Or maybe you don't need it if its one time
Drush is relatively simple
Demo

Thanks!
