How to Migrate Content with Custom Fields
IntermediateQuick Answer
TL;DR
Migrating custom fields requires mapping each source field to a corresponding field in your new CMS schema. Export custom field data alongside your content, write transformation scripts to convert data types and formats — date strings, relationship IDs, select options — and validate that all field data imports correctly. Repeater fields, flexible content blocks, and relationship references need special handling and should be tested thoroughly before production cutover.
Key Takeaways
- Create a field-by-field mapping document before writing a single line of migration code
- Handle data type conversions explicitly: dates, booleans, references, and arrays all need transformation logic
- Repeater fields and flexible content blocks require recursive transformation scripts
- Validate imported data against schema constraints to catch mapping errors early
