All-in-One WP Migration Unlimited Extension is a great tool for migrating WP sites. It works perfectly with all sorts of WP sites – hosting platforms, plugins, themes, it doesn’t matter. Uploading to new platforms is done in chunks to bypass upload restrictions on some servers. The process is very simple. After installing and activating the plugin, select All-inOne WP Migration in the sidebar and click “Export”. Then you need to select “Export to” – export to a file (download a file) or export using one of the following plug-in services.
