+# Database Migrations
+
+This directory contains SQL migration scripts for the User Service database schema.
+
+## Migration Files
+
+### 20260126_add_multi_tenancy_support.sql
+Adds multi-tenancy support by adding `tenant_id` column to all user-related tables:
+- users
+- user_profiles
+- user_contacts
+- verification_codes
+
+**Rollback**: Use `20260126_add_multi_tenancy_support_rollback.sql`
+
+## How to Run Migrations
+
+### Using Docker
+
+```bash
+# Run migration
+docker exec iconsulting-postgres psql -U postgres -d iconsulting -f /path/to/migration.sql
+
+# Or copy file and run
+docker cp migration.sql iconsulting-postgres:/tmp/
+docker exec iconsulting-postgres psql -U postgres -d iconsulting -f /tmp/migration.sql
+```
+
+### Using psql directly
+
+```bash
+psql -U postgres -d iconsulting -f migration.sql
+```
+
+### From the project root
+
+```bash
+# Run migration on server
+ssh user@server "docker exec iconsulting-postgres psql -U postgres -d iconsulting" < migration.sql
+```
+
+## Rollback Migrations
+
+To rollback a migration, use the corresponding `*_rollback.sql` file:
+
+```bash
+docker exec iconsulting-postgres psql -U postgres -d iconsulting -f rollback_migration.sql
+```
+
+## Migration History
+
+| Date | Migration | Description | Status |
+|------|-----------|-------------|--------|
+| 2026-01-26 | add_multi_tenancy_support | Added tenant_id to user tables | ✅ Applied |
+
+## Best Practices
+
+1. **Always backup before running migrations in production**
+2. **Test migrations in development first**
+3. **Keep rollback scripts updated**
+4. **Document all schema changes**
+5. **Use transactions when possible**
+
+## Verification
+
+After running a migration, verify the changes:
+
+```bash
+# Check if column was added
+docker exec iconsulting-postgres psql -U postgres -d iconsulting -c "\d users"
+
+# Check indexes
+docker exec iconsulting-postgres psql -U postgres -d iconsulting -c "\di idx_users_tenant*"
+```
