CMS migrations fail or underperform for predictable, repeated reasons. This guide covers the most common pitfalls across any CMS-to-CMS migration, helping you avoid them proactively.
Pitfall 1 — Underestimating Content Mapping Complexity
Different CMS platforms model content differently — a WordPress custom field might not have a clean equivalent in the target platform. Thoroughly map every content type and field before starting, rather than discovering gaps mid-migration.
Pitfall 2 — Losing SEO Value from Missing Redirects
URL structures almost always change — every previously-indexed URL needs a corresponding redirect to its new location, or you lose accumulated search ranking value. Build a complete redirect map before cutover, not as an afterthought.
Pitfall 3 — Not Accounting for Theme/Template Rebuild Time
Themes and templates are rarely portable between CMS platforms — teams frequently underestimate how much design/frontend work is needed to recreate the existing site's look and functionality in the new platform.
Pitfall 4 — Migrating Directly to Production
Never perform the actual migration work directly on a live domain — build and thoroughly test on a staging environment first, catching issues before they affect real visitors.
Pitfall 5 — Forgetting About Third-Party Integrations
Analytics tracking, marketing pixels, email service integrations, and other third-party connections need to be re-implemented in the new platform — audit everything currently integrated before migrating, not just core content.
Pitfall 6 — Not Testing Forms and Interactive Functionality Thoroughly
Contact forms, search functionality, and other interactive features need explicit testing in the new platform — don't assume they "just work" the same way as before.
Pitfall 7 — Migrating User Accounts Without a Clear Password Strategy
Password hashes typically aren't portable between different CMS platforms — plan explicitly for how existing users will regain access (typically a forced password reset flow).
Pitfall 8 — No Rollback Plan
Always keep the old site/server available and unchanged until you're fully confident the new site is stable — a migration without a rollback option turns any post-cutover issue into a crisis rather than a manageable problem.
Pitfall 9 — Ignoring Media/File Migration Details
Image and file URLs referenced within content need updating if the new platform uses a different media path structure — a common source of broken images post-migration if not handled systematically.
Pitfall 10 — Insufficient Post-Migration Monitoring
Watch analytics, error logs, and search console data closely in the weeks following migration — catching a systemic issue (like a broad redirect problem) early limits the damage compared to discovering it a month later.
A Pre-Migration Checklist
- Complete content type/field mapping documented
- Full redirect map built and tested
- Theme/template rebuild scoped and budgeted for realistically
- All third-party integrations inventoried and planned for
- Staging environment fully tested before any production cutover
- Rollback plan documented and the old environment preserved
