CMS_Tree, CMS_Document, and coupled data tables), while Optimizely is code-first, requiring all content types to be defined as strongly typed C# classes (PageData, BlockData) in PaaS or registered via the Content Definitions API in SaaS before any content can be imported. This fundamental mismatch means the migration is a strict two-phase effort: first rebuilding all content type schemas in Optimizely, then extracting data from Kentico via direct SQL and transforming it for ingestion through Optimizely's Content Management API. The most technically demanding transformation is parsing Kentico's page builder widget JSON and remapping it into Optimizely's typed ContentArea and BlockData property model. These are the architectural mismatches and technical hurdles specific to a Kentico to Optimizely migration.
Optimizely rejects content imports for any type not pre-defined as a C# class or API-registered definition, meaning all Kentico page types must be fully rebuilt in the target system before data migration can begin.
Every Kentico content type requires a custom SQL extraction query joining CMS_Tree, CMS_Document, and the per-type coupled table, making bulk export via Kentico's native REST API or Site Export Wizard unreliable for cross-platform migrations.
Kentico stores all page builder layout and widget configuration in a deeply nested JSON blob in DocumentPageBuilderWidgets, which must be parsed and remapped widget-by-widget into Optimizely's typed ContentArea and BlockData structures.
Any Kentico LongText field storing HTML must be mapped to Optimizely's XhtmlString type rather than a plain string, or internal link resolution and rich text editor recognition will silently fail.
Kentico media files and page attachments stored on the filesystem or as database BLOBs must be extracted, uploaded individually via Optimizely's media API, and then re-referenced by their new Content IDs throughout the migrated content.
Kentico's native hierarchical category tree (CMS_Category) has no direct equivalent in Optimizely and must be redesigned as a custom taxonomy content type or tag-based property before page-to-category relationships can be migrated.
Our migration engineer precisely maps every data point from Kentico to Optimizely, ensuring perfect continuity for your customer support operations.

“One of the easiest migrations I've ever been through. The team took care of everything — all our data, customer interactions and macros. The process was clear, straightforward and we felt supported all the way. An absolutely seamless experience for our support team and our customers.”
“Fantastic at both guiding us through the process and helping us fix things as they come up and dial them in.”
“The ease of the process and that ClonePartner was informing me what was going on at every step. If you're on the fence, do it. ClonePartner are great!”
“They were SO helpful. We had a few hiccups because our migration was in the middle of the process, but they were really flexible and did multiple delta migrations for us. We were able to map a lot of our old ticket data so it's usable for comparisons in the future.”
“Overall a great experience. We had to go back a few times to get everything just right, which was totally expected. The transition was smooth, and there was no data loss.”

Kentico to Optimizely Migration: A Technical Guide
Kentico to Optimizely migration requires SQL extraction from Kentico's three-table-join structure, explicit content type mapping, and import via Optimizely's Content Management API. No automated converter exists.
Export Guide
How to Export Data from Kentico: Extraction Methods, API Limits & Portability
Kentico data extraction requires combining methods: direct SQL for content, filesystem copy for media, REST or CI for config. The REST API can't paginate pages, and the Site Export ZIP is Kentico-native only.
Choosing the right approach is key because migrating from Kentico to Optimizely isn't just about moving data – it's about protecting your content, SEO, and reader experience.
