CMS Migration Checklist (Step-by-Step)
1. Pre-Migration Planning (Most Important Phase)
This is where most failures happen.
Define Your Migration Goals
- Better performance?
- Improved SEO?
- New design or UX?
- Switching CMS (e.g., WordPress → Headless)?
Be clear. Migration without a goal = chaos.
Full Website Audit
Audit everything before touching your site:
- URLs (crawl with Screaming Frog)
- Top-performing pages
- Backlinks
- Indexing status
- Technical issues
Example Audit Table
| Element | Tool | Purpose |
|---|---|---|
| URLs | Screaming Frog | Crawl structure |
| Traffic | Google Analytics | Identify top pages |
| Keywords | Ahrefs / SEMrush | Ranking analysis |

✅ Backup Everything
- Database
- Media files

2. URL Mapping & Redirect Strategy
This is the #1 SEO-critical step.
Create a URL Mapping Sheet
| Old URL | New URL | Redirect Type |
|---|---|---|
| /blog/seo-tips | /seo-tips | 301 |
| /services | /our-services | 301 |
Use 301 Redirects

⚠️ Never use 302 unless temporary.

Before migration, lock these down:
On-Page SEO Elements
- Title tags
- Meta descriptions
- Header structure (H1–H6)
- Internal linking
- Image alt text
Technical Setup
- XML sitemap
- Robots.txt
- Canonical tags
- Structured data
Internal Linking Strategy
Link to relevant pages like:
