Migration of balldecor.ru to HAIH

Objective

Transfer the active BallDecor website to HAIH while preserving search visibility, commercially significant content, and core interaction workflows, without migrating the legacy architecture as-is.

What is important to preserve

• active indexed URLs and their search value;
• key business directions: event decoration, balloon delivery, printing/branding, seasonal and event services;
• telephone numbers, request forms, callback/contact workflows, and available communication methods;
• images and content that actively contribute to organic traffic and service sales;
• historical links from search and external sources via 1:1 URLs or correct 301 redirects.

What needs to be rebuilt

1. Inventory the current website: routes, page templates, data, forms, integrations, assets, and actual runtime.
2. Extract the domain core and implement it on HAIH using modern vertical slices.
3. Do not copy legacy technical debt unless it serves as an external contract.
4. Preserve or improve SSR/indexability, metadata, canonical tags, sitemap, robots.txt, structured data, and loading speed.
5. Reproduce forms and lead generation, and verify the delivery of requests and contacts.
6. Before switching, perform a full crawl of the old website and the new staging environment, mapping URLs, status codes, titles, H1 tags, canonicals, links, assets, and forms.
7. After launch, check 301 redirects, 404 errors, sitemap/robots.txt, search accessibility, and analytics.

Definition of Done

The new balldecor.ru runs on HAIH, core user and commercial workflows are verified, SEO migration contracts are checked, significant old URLs are not lost, forms and analytics are operational, and further marketing improvements can be performed independently of the technical legacy.
