Inventory, data transfer, switchover
Every migration starts with an inventory. We pull the full URL list from sitemaps, server logs and analytics, then record content types, media, forms, user accounts and everything connected to third party systems. From that we build a field by field mapping from the old model to the new one.
Next comes a test migration on a separate environment. That is where you find out which character encodings break, which images lose their references and which special cases in the old system were never documented. We repeat the run until the result is clean, because the real switchover should hold no surprises.
Before the move we lower the TTL on the DNS records, briefly freeze editing, transfer the last content changes and switch. Immediately afterwards we verify redirects, form delivery, site search, payment and shipping interfaces, and whether the new site can be indexed. The old system stays reachable until the new one runs steadily, and its final backup stays archived.
