Data Cleanup for Content Migrations: A Practical Workflow

By WTools TeamFebruary 21, 202610 min read

Content migrations fail when inputs are inconsistent. Titles are messy, slugs collide, and legacy formatting breaks rendering. This workflow keeps your migration stable by applying consistent cleanup rules.

Step 1: Normalize spacing

Fix spacing first so later rules behave predictably. Use Remove Extra Spaces and Remove Empty Lines.

Step 2: Replace legacy patterns

Use Find and Replace to remove deprecated tags, old product codes, or broken entities.

Step 3: Generate clean slugs

Create URL-safe slugs with Slug Generator and ensure uniqueness before importing into the CMS.

Step 4: Validate final output

Spot-check samples and run automated validation rules. Confirm no empty titles, duplicate slugs, or invalid characters remain.

Migration checklist

  • Normalize whitespace
  • Replace legacy tokens
  • Generate clean slugs
  • Validate sample data
  • Run import in small batches
