1. Underestimating Data Migration
Product data, customer accounts, order history, SEO URLs — migration is more than just moving files. Plan for data mapping, validation, and testing well in advance.
2. Ignoring SEO During Migration
Failing to set up proper 301 redirects can destroy years of SEO work overnight. Map every old URL to its new equivalent and monitor search console closely after launch.
3. Skipping Performance Testing
Your new platform may perform well with test data but struggle under real-world load. Always conduct load testing with production-like data volumes before going live.
4. No Rollback Plan
Hope for the best, plan for the worst. Having a tested rollback strategy gives you confidence and reduces risk significantly.
5. Big Bang vs. Phased Approach
Trying to migrate everything at once increases risk exponentially. Consider a phased approach — migrate core functionality first, then add features incrementally.
