How to Migrate Content Between Different CMS Platforms

מאגר מידע

Migrating content between fundamentally different CMS platforms (not just versions of the same platform) requires careful planning around content mapping, URL preservation, and data integrity. This guide covers a systematic approach.

Building on General Migration Guidance

See How to Migrate from WordPress to Another CMS and Common CMS Migration Pitfalls and How to Avoid Them for foundational context — this article focuses specifically on the content mapping and technical transfer mechanics applicable across various platform combinations.

Step 1 — Audit and Document Current Content Structure

Before migrating, thoroughly document your source platform's content types, fields, taxonomies, and relationships — you need a clear picture of what exists before you can plan how it maps to the target platform's different content model.

Step 2 — Map Content Types Between Platforms

Source Concept	Target Platform Equivalent
Source: Custom post type	Target: Custom content type/entity bundle
Source: Category/tag taxonomy	Target: Taxonomy term reference field

Different platforms model content differently — a direct 1:1 mapping isn't always possible; document where genuine adaptation is needed rather than assuming a clean automatic translation.

Step 3 — Export Content from the Source Platform

drush export:content --format=json > content-export.json

Most platforms offer some form of content export (native tools, or via direct database query if needed) — export to a structured, intermediate format (JSON/CSV) that you can then transform for the target platform.

Step 4 — Transform Content to Match Target Structure

const transformedContent = sourceContent.map(item => ({
  title: item.post_title,
  body: convertContentFormat(item.post_content),
  published_date: item.post_date,
  taxonomy: mapCategories(item.categories),
}));

A transformation script converts source data structure to match your target platform's expected import format — the specific transformation logic depends entirely on your specific source/target platform combination.

Step 5 — Import into the Target Platform

Use the target platform's native import tools/API where available, or direct database insertion via its provided APIs (never direct raw database manipulation bypassing the platform's own data layer, which risks data integrity issues).

Step 6 — Preserve URL Structure or Set Up Redirects

See How to Set Up Redirects and Rewrites for a Static Site for the general redirect principle, applicable here too — either preserve the exact same URL structure in the new platform, or build a comprehensive redirect map from old URLs to new, preserving SEO value and avoiding broken links for existing bookmarks/backlinks.

Step 7 — Migrate Media/Assets

Don't forget uploaded images/files — these need to be transferred and, if URL structure changes, referenced correctly in the migrated content; a common oversight is migrating text content while leaving media references broken.

Step 8 — Verify Content Integrity After Migration

Systematically spot-check migrated content against the source — verify formatting, embedded media, and metadata transferred correctly; don't assume a successful import process means genuinely correct content without actual verification.

Step 9 — Test Thoroughly Before Cutover

See How to Migrate an E-commerce Store to a New VPS Without Downtime for related migration cutover principles — test the migrated site thoroughly on the new platform before pointing your live domain at it.

Common Errors

Rich text content displays with formatting issues after migration — different platforms often use different rich text/HTML conventions internally; verify your transformation logic correctly converts between source and target formatting conventions, not just transferring raw text.
