Duplicator Migration
Verified Before
DNS Changes.
Duplicator packages your complete WordPress site for migration between hosts. The packaging almost always succeeds. The failure points are on the destination: PHP compatibility, disk space, database credentials, file permissions. We check all of these before the migration starts.
CV Infotech handles the full Duplicator migration process, from pre-migration server compatibility check through to full page verification before DNS is switched.
What Duplicator Does and Where Migrations Fail
Duplicator packages your entire WordPress site, all files and the complete database, into a single archive alongside an installer script (installer.php) that can recreate the complete site on a different server or domain. The plugin generates the archive on your source server, you upload both files to the destination, run the installer from a browser, and it handles database import, file extraction, and URL updating for the new location. The packaging step almost always works without issue.
The failure points are on the destination server: a PHP version difference that makes certain operations unavailable, insufficient disk space for the full unpackaged site, database connection credentials that differ from the source, file permission settings that prevent the installer from writing files, and server resource limits like max_execution_time or memory_limit that cause the installer to time out during database import. All of these can be identified and addressed before the migration starts with a five-point destination check.
The most avoidable migration mistake is switching DNS before verifying the migrated site fully. Once DNS propagates and visitors start reaching the new location, discovering that a form does not submit, that images are broken, or that the checkout flow fails means fixing issues on the live site under real load. We verify every relevant page type on the destination's temporary URL before recommending the DNS switch.
Server Compatibility Checked First
PHP version, disk space, database access, and file permission settings are verified on the destination before packaging begins.
Large Site Timeout Handling
Very large sites may need server resource limit adjustments to prevent the packaging or installer step from timing out mid-process.
URL Rewriting Handled
All hardcoded URLs in the database are updated for the new domain as part of the installation process, with verification afterward.
DNS Only After Full Verification
Every page type, including forms, media, and WooCommerce checkout if applicable, is verified on the temporary URL before DNS is touched.
What We Cover In A Duplicator Migration
Destination Server Compatibility Check
PHP version, disk space, database credentials, and file permissions on the destination verified before any package is created.
Package Creation and Timeout Handling
Duplicator package created with server resource limits adjusted if necessary for large sites, preventing the timeout errors that cause incomplete packages.
Installer Configuration on Destination
Package and installer.php uploaded to destination, installer run with correct database configuration for the new environment.
URL and Database Rewriting
All hardcoded source URLs in the database updated to the destination URL or temporary URL during installation, with verification afterward.
Post-Migration Verification
All page types tested via temporary URL: homepage, internal pages, forms, media, WooCommerce checkout where applicable, and user login.
DNS Switch Recommendation
DNS change recommended only after full verification is complete, with rollback path confirmed if anything unexpected is discovered after propagation.
Why CV Infotech For Duplicator Migration
Duplicator makes the packaging step simple enough that it is tempting to treat the whole migration as simpler than it is. The package creates successfully, the installer runs, and WordPress loads on the new host. The issues that appear afterward, a broken form, missing media files, a WooCommerce checkout that silently fails for a specific payment method, are the kind that only show up when every page type is tested rather than assumed to work because the homepage loaded.
We verify systematically before recommending the DNS change, not because most migrations fail catastrophically, but because the issues that do appear are much easier to fix when the original site is still reachable and the new one is being tested via a temporary URL.
This service is not the right choice if:
- You need ongoing recurring backup protection, see /wordpress-plugins/updraftplus/
- Your site is a WordPress Multisite network, which requires a more complex migration approach than standard Duplicator
- Your hosting destination requires a manual cPanel or server admin approach that the Duplicator installer cannot handle

How A Duplicator Migration Works
We verify PHP version compatibility, available disk space, database access credentials, and file permission settings on the destination server before touching the source site, since any of these differences can cause a migration to fail partway through.
A complete backup of the source site is created before packaging starts, since the package creation process itself is non-destructive but a fallback is essential if something unexpected occurs at any point in the migration.
The Duplicator package is created from the source site, including all files and the complete database. For very large sites, server resource settings may need adjustment to prevent timeout during packaging.
The package and installer.php are uploaded to the destination server and the installer is run, handling database import, file extraction, and URL rewriting for the new location.
Every page type is tested on the new environment via the temporary URL before DNS is changed, including forms, any eCommerce checkout paths, media files, and user login, since migrating first and testing afterward means discovering issues with the live site already redirected.
