1. Start with the site’s actual dependencies
A hosting move affects more than page files. Your review should identify the website platform, database, media, forms, redirects, DNS records, SSL configuration, analytics and any services that receive inquiries. Bosseo’s public Dedicated Hosting page says its migration work includes files, database, DNS, SSL and email records. Those are useful categories for a pre-migration inventory, but your firm should still require a written list of what applies to your site.
Recommended approach
Ask Bosseo to document every production dependency, the owner of each account, the DNS changes required and the test that will confirm each item works. Do not approve a cutover based only on a general statement that the site was copied.
