Issue while generating db_schema file for existing module Magento 2.3.1

Question

I have installed fresh Magento 2.2.6 and i have installed two custom modules.

Then i have upgraded the Magento Version to 2.3.1 now i am trying to generate db_schema file for those module using below command.

php bin/magento setup:install --convert-old-scripts=1

Error:

[Symfony\Component\Console\Exception\RuntimeException]

The "--convert-old-scripts" option does not exist.

1 has InsallSchema,UpgradeSchema, another has only UpgradeData — Ashish Viradiya

Run the below command

php bin/magento setup:install --convert_old_scripts=1

Instead of

php bin/magento setup:install --convert-old-scripts=1

For more information. Look at this

Guess this would be issue for your case.

EDIT :

Run this command in your root to check the available options there

php bin/magento setup:install -h

then you'll probably will get this

--convert-old-scripts[=CONVERT-OLD-SCRIPTS]

so run accordingly of whatever available for your version.

I have checked with fresh 2.3.1 setup the option convert-old-scripts is displaying but in the upgraded setup there are no convert-old-scripts found. — Ashish Viradiya
