The Hidden Cost of “Free” Hosting Migrations
"Free migration" is a strong incentive to switch hosts, and most of the time the offer is genuine — a specialized team really will copy your files, database, and email over at no charge. What "free" doesn't cover, and rarely mentions, is everything adjacent to the copy itself, which is where the actual risk and effort in switching hosts tends to live.
What a Free Migration Typically Includes
In its usual scope, a free migration service copies: website files, the database, and sometimes email accounts and their existing messages, from the old host to the new one, using automated tools or a migration specialist working through a support ticket. For a simple, self-contained WordPress site with no unusual customizations, this genuinely can be close to a complete, painless solution.
What It Almost Never Includes
The gaps tend to cluster around anything environment-specific rather than data-specific:
- PHP version and extension differences. If the old host ran PHP 8.1 with certain extensions enabled and the new host defaults to a different version or configuration, plugins or custom code can break silently after migration — something a generic file-copy tool has no way to detect or fix.
- Cron jobs. Scheduled tasks configured directly in the old host's control panel (rather than through WordPress's internal cron) typically don't transfer automatically and need to be manually recreated on the new server.
- DNS cutover timing. The migration team can copy your data, but they don't control your domain's DNS unless you explicitly hand that over too — and a mistimed or forgotten DNS change is one of the most common sources of post-migration downtime.
- SSL certificate reissuance. A certificate tied to the old server's validation setup often needs to be reissued on the new server, and if this isn't handled proactively, sites launch on the new host with a broken or missing certificate.
- Third-party integrations tied to the old IP. Payment gateways, API allowlists, or firewall rules referencing the old server's IP address need manual updates that a migration tool has no visibility into.
- Email continuity during cutover. Even with mailboxes copied, in-flight email during the DNS propagation window can be delivered to whichever server currently resolves for a given visitor's DNS resolver, occasionally causing a handful of messages to land on the old server after the "migration" is technically complete.
Why This Isn't Necessarily Deceptive
None of these gaps are usually hidden maliciously — they're just genuinely hard to automate generically across every possible site configuration, and "free migration" was never marketed as "we will audit and fix your entire technical environment." The offer is accurate as far as it goes; the issue is that "as far as it goes" is narrower than most customers assume when they hear the word "free."
When Paying for a Managed Migration Makes Sense Anyway
None of this is an argument against free migrations in general — for a large share of straightforward sites, they genuinely deliver on the promise with minimal fuss. The calculation changes for accounts with real complexity: custom code beyond a standard WordPress install, multiple interconnected subdomains or add-on domains, non-standard cron-driven integrations, or e-commerce stores where even a few hours of order-processing disruption carries real financial cost. For those cases, a paid, white-glove migration service — where a specialist audits the source environment in detail before touching anything, rather than running a generic automated tool — is often worth the additional cost precisely because it converts an unknown number of post-migration surprises into a known, budgeted line item handled by someone actively looking for the account's specific quirks in advance.
How to Migrate With Fewer Surprises
A short pre-migration checklist meaningfully reduces risk: document any server-level cron jobs before migrating, so they can be recreated manually; note the exact PHP version and any custom php.ini settings in use; lower your domain's DNS TTL a few days before the migration to shrink the propagation window; and test the site on the new server using a local hosts-file override (pointing your own machine at the new IP before DNS actually changes) so you can catch environment issues before real visitors are affected.
A Realistic Post-Migration Checklist
After any migration — free or paid — a short verification pass catches most of the gaps described above before real visitors do: submit a test order or form on the new server to confirm database writes are working correctly; send a test email to and from the new server to confirm mail routing wasn't left pointing at the old configuration; check the SSL certificate's validity and expiration date directly in a browser, since a stale or missing certificate is one of the most visible and immediate post-migration failures; verify any scheduled tasks (WooCommerce subscription renewals, automated report emails, cache-warming crons) actually ran on their expected schedule during the first week; and check server error logs directly for any recurring PHP warnings that weren't present before, which often indicate a version or extension mismatch between old and new environments. None of these checks are difficult individually, but skipping them collectively is exactly how "the migration went smoothly" turns into "three days later, orders stopped processing and nobody noticed."
The Takeaway
A free migration service is a genuinely useful, cost-saving offer for the specific job it does — moving your files and database. It's not a substitute for understanding what else depends on your hosting environment, and the gap between those two things is exactly where most "the migration went wrong" stories originate.
