Migrate to declarative schema

Question

people. I'm trying to migrate to declarative schema on my module with magento v2.3.1. But when i'm running php bin/magento setup:install --convert-old-scripts=1 it doesn't generates any db_schema.xml. What i'm doing wrong?

Answer 1

Try to remove your module from setup_module table and rerun the command.

As far as I understand, Magento analyzes DDL commands called during setup:upgrade to generate the schema.

In your case, I assume, the legacy install scripts are not being executed.

Answer 2

In order to migrate your install and upgrade schema of already installed module to db_schema.xml follow below steps

• Remove your module entry from setup_module table
• Drop all your module tables as mentioned in your install and upgrade schema
• Execute php bin/magento setup:upgrade --convert-old-scripts=1
