Moving platforms without losing rankings or data
CMS migrations planned around SEO preservation, content integrity, and minimal downtime.
A CMS migration is one of the highest-risk projects a website goes through, not because moving content is technically hard, but because every URL that changes without a proper redirect is a potential loss of ranking equity that took months or years to build. The risk isn't in the platform switch itself - it's in what gets skipped under deadline pressure, like a redirect map that's 90% complete instead of 100%, or a content field that doesn't map cleanly and gets dropped rather than fixed.
Done properly, a migration preserves what already works while fixing what didn't - it's also the natural moment to address technical debt that's been deferred because touching the old platform felt too risky.
A CMS migration moves a site's content and structure from one platform to another while preserving SEO equity through careful URL mapping and redirects, ideally with minimal downtime.
What we bring to this
Migration Planning
- Full content and data inventory before touching anything
- Field-by-field mapping between old and new platforms
URL Mapping & Redirects
- Complete old-to-new URL mapping, not a partial one
- 301 redirect implementation and validation
SEO Equity Preservation
- Pre-migration ranking and traffic baseline
- Post-migration monitoring against that baseline
Staged Rollout
- Staging environment migration and QA before production
- Rollback plan in case something goes wrong
Scope of work
| Area | What's included |
|---|---|
| Content Migration | All content, media, and metadata moved and validated on the new platform |
| URL & Redirect Strategy | A complete URL map and 301 redirect implementation |
| SEO Monitoring | Pre- and post-migration ranking and traffic comparison |
| Rollback Plan | A documented fallback if the migration needs to be reversed |
The engagement, step by step
Content & URL Inventory
We catalogue every existing page and URL before planning anything, since an incomplete inventory is the most common cause of a missed redirect.
Field & Content Mapping
Content fields on the old platform are mapped to their equivalent on the new one, with a plan for anything that does not map cleanly.
Redirect Strategy
A full 301 redirect map is built and tested before go-live, covering every URL that will change.
Staging Migration & QA
The migration runs on staging first, where content, redirects, and functionality are checked before production is touched.
Production Cutover
We migrate production on a schedule designed to minimise downtime, with a rollback plan ready if something does not go as expected.
Post-Migration Monitoring
Rankings and traffic are tracked against the pre-migration baseline so any issue is caught within days, not months.
How this compares
| Planned Migration | Rushed Migration |
|---|---|
| Every URL has a mapped redirect | Redirect map is partial or built after launch |
| SEO baseline tracked before and after | No baseline, so ranking loss is discovered late |
| Staging QA catches issues before production | Issues are found by users after go-live |
The projects that lose rankings are almost never the ones that took too long - they're the ones that skipped the redirect map to hit a deadline.
Where this fits
- A business is replatforming from a legacy CMS and cannot afford to lose existing organic rankings
- A site is consolidating multiple platforms into one and needs a clean content and URL merge
- A company is moving off a CMS that no longer meets its content or security needs
Who needs this
Sites with meaningful existing organic traffic
The more ranking equity currently in place, the more a careless migration stands to lose.
Businesses consolidating multiple sites or platforms
URL mapping gets more complex with more source systems, which makes planning more important, not less.
What changes for you
- SEO equity carries over instead of resetting to zero on the new platform
- Downtime is minimised through staged rollout rather than a single risky cutover
- Technical debt gets addressed during the move instead of carried forward again
Why work with EASI7 on this
- We build the complete URL map before migration starts, not as a post-launch cleanup task
- We track a real ranking and traffic baseline so any post-migration issue is caught early, not discovered a quarter later

Common questions
Only if it's done carelessly. Done properly - with a full URL map and 301 redirects planned before the move, not after - ranking equity carries over with minimal disruption. The risk is almost always in what gets skipped under time pressure, not in the migration itself.
It depends heavily on site size and content complexity - a small site might move in a few weeks, while a large catalogue or content library with complex field mapping can take a couple of months to do properly.
We can guarantee we plan for minimal downtime and a clear rollback path, but promising zero downtime on every migration would be dishonest - the goal is a short, controlled window rather than an unplanned one.
We flag those cases during the mapping phase rather than discovering them mid-migration. Some content gets restructured to fit the new model; in rare cases, content that genuinely has no home gets a documented decision rather than being silently dropped.
In practice yes, though the amount of custom mapping work varies a lot depending on how different the two platforms' content models are. We scope that during planning rather than assuming every migration is equally straightforward.

We'll build the full URL and redirect map before anything goes live, not after.
