Using the Engine Configuration Transfer you can copy an export of your Engines from one installation and paste it into the Import of another.
Note: Any existing Engine will be overwritten!
After an Engine configuration has been imported you should rebuild the Index using the Rebuild Index button on the Engines tab of the SearchWP settings screen.
If you need support you can open a ticket from the Support tab.
Please note that the support tab is available only after activating the license in the Settings page.
