How to hire a developer to migrate your website to a new CMS
If you want a smooth CMS migration, hire a developer who has completed full website migrations before, not just general web development. The right person will handle content transfer, URL mapping, redirects, testing, SEO protection, and launch support while keeping downtime and risk low.
What a CMS migration developer should do
Audit your current website and identify all content, templates, media files, metadata, and URLs that need to move.
Map the old site structure to the new CMS structure so content lands in the right place.
Back up the full site before migration, including the database, media, and configuration files.
Set up a staging environment and test the migration there before touching production.
Build and validate 301 redirects so old URLs point to the correct new pages and SEO value is preserved.
Test forms, internal links, metadata, analytics, and integrations before launch.
Monitor the site after launch for crawl errors, broken links, missing content, and performance issues.
Skills to look for
CMS experience with both the platform you are migrating from and the platform you are migrating to.
Migration planning skills, including content audits, phased rollouts, and risk management.
SEO knowledge to preserve rankings through redirects, metadata validation, and sitemap updates.
Backend and scripting expertise to automate imports, exports, field mapping, and data transformations when needed.
Testing discipline to validate redirects, forms, page rendering, and integrations in a staging environment before launch.
Clear communication to coordinate with designers, marketers, SEO specialists, and stakeholders throughout the project.
How to define the role before hiring
Before you begin searching, prepare a short migration brief. This helps attract the right developer and reduces the likelihood of mismatched candidates.
Include:
Your current CMS and the new CMS you plan to migrate to.
The number of pages, blog posts, products, media files, and any custom content types.
Whether you need a complete rebuild, a partial migration, or a phased rollout.
Whether SEO preservation, multilingual content, custom templates, or third-party integrations are critical.
Your timeline, launch window, budget, and the internal team members involved.
Interview questions that reveal CMS migration expertise
Which CMS migrations have you completed recently, and what was your role?
How do you build and validate a redirect map before launch?
How do you handle content mapping when the source and destination CMS use different field structures?
What steps do you take to preserve SEO during migration?
How do you test a site in staging before switching DNS?
What do you monitor after launch, and for how long?
Red flags to avoid
The developer plans to migrate directly to production without using a staging environment.
They do not mention backups or a rollback strategy.
They treat redirects as an afterthought instead of a core part of the migration.
They have no process for testing forms, analytics, or search engine indexing after launch.
They cannot clearly explain how they will preserve content structure, metadata, and URL equity.

Best hiring process for a CMS migration
Start with a migration audit and create a complete inventory of your existing website.
Write a detailed job brief that outlines your CMS platforms, project scope, timeline, and SEO requirements.
Shortlist candidates with proven CMS migration experience rather than only general front-end development experience.
Request a migration plan covering backups, staging, testing, redirects, rollback procedures, and post-launch monitoring.
Select a developer who can collaborate effectively with your marketing, SEO, and stakeholder teams throughout the migration.
What success looks like
All important content is transferred accurately to the new CMS.
Every old URL redirects to the appropriate new page without redirect chains or loops.
The website functions correctly, forms work, and analytics continue tracking as expected.
Organic search visibility remains stable, with crawl errors identified and resolved quickly after launch.
Your internal team can confidently manage the new CMS following handover and training.
The best CMS migration developer combines strong technical expertise with a disciplined migration process. By clearly defining your requirements, evaluating migration-specific experience, and insisting on staging, testing, backups, redirects, and SEO safeguards, you can significantly reduce the risk of a costly migration failure.
