Drupal 8 MigrationStep by step explanation with live demo

ProcessI am importing d 7 press release to d 8

I have created “press” type in d8

I have created fields in d8

I created a d8 module (almost blank)

Six steps in code, saved as git branches to show migration one field at a time.

Between each step I use a script to reset the d8 database to pre import state.

I will switch to each branch > explain the code > run migration > reset the database.
