DBIS Monorepo Migration

Automated Migration

Single Project

./scripts/dbis/automate-dbis-migration.sh dbis_core dbis_monorepo packages

What it does:

• Copies project to monorepo
• Updates package.json name
• Creates migration notes
• Provides next steps

All Projects

./scripts/dbis/migrate-all-dbis-projects.sh dbis_monorepo

What it does:

• Migrates all DBIS projects
• Creates migration notes for each
• Provides comprehensive next steps

Manual Steps After Automation

1. Update Dependencies

   cd dbis_monorepo/packages/dbis_core
   # Edit package.json to use @dbis/* and @workspace/* packages
   

2. Update Imports

   // Before
   import { User } from '../types';
   
   // After
   import { User } from '@dbis/shared-types';
   

3. Test Build

   cd dbis_monorepo
   pnpm install
   pnpm build
   

4. Test Tests

   pnpm test
