Coming from Doctrine/Migrations

[VincentLanglet]

HI,

I just discovered this lib and it seems great.
But I already have doctrine migrations.

What could be great would be having some doc about how to migrate from Doctrine to this lib

• How to rewrite existing migrations (if needed)
• How to migrate the existing migrations table
• How to migrate some config

(Also the rollup command from doctrine is nice, having the same here would be great).

I opened our old MR where we did exactly this and here are some core steps we did:

• Migrated existing migrations by this simple replace
  • This assumes empty down method and very basic bodies
• Dropped old migrations table from doctrine/migration and created & filled new table via:
  • bin/console migration:init
  • bin/console migration:skip
• Replaced CI runs
  • bin/console doctrine:migrations:migrate -> bin/console migration:run both
  • bin/console doctrine:migrations:status -> bin/console migration:check
• Registered new services:

  ShipMonk\Doctrine\Migration\MigrationCheckCommand:
  ShipMonk\Doctrine\Migration\MigrationGenerateCommand:
  ShipMonk\Doctrine\Migration\MigrationInitCommand:
  ShipMonk\Doctrine\Migration\MigrationRunCommand:
  ShipMonk\Doctrine\Migration\MigrationSkipCommand:
  ShipMonk\Doctrine\Migration\MigrationService:
    $migrationsDir: "%kernel.project_dir%/migrations"
    $migrationClassNamespace: 'SHipMonk\Migration'
    $migrationClassPrefix: 'Version'
    $templateFilePath: "%kernel.project_dir%/migrations/migration.template"

• Changed the template like this:
