Migrating to a new flight simulator has never been so easy!

Screenshot of Migration ToolFrom the early days of flight simulation, each new simulator has meant the need to replace almost all addons with new ones, often at a high cost, and in many cases no upgrades have been available at all.

FSX to Prepar3D Migration Tool is a revolutionary tool that allows you to install Flight Simulator X (FSX) addons into any version of Prepar3D, as well as old Prepar3D addons into the newest version of the simulator.

Get it from simMarketNo manual editing is necessary, nor it is necessary to have FSX present on the computer. Just install the tool, follow its manual and install addons like you would install them into FSX. Everything from freeware Pipers to the most complex addons will appear in Prepar3D.

Get it from FSPilotShopWith Migration Tool, you will be able to enjoy the best of both worlds – excellent FSX addons in evolving Prepar3D flight simulator.

How does it work?

Migration Tool redirects installers of FSX and old Prepar3D addons to the latest Prepar3D. Run an installer as if you were be installing something into FSX, and the contents will show up in Prepar3D instead.

In addition, Migration Tool installs a module for Prepar3D that monitors the simulator as it is running and steps in to make changes in real time where necessary to help older addons find correct files, folders and settings.

Migration Tool has been tested with many popular sceneries, aircraft and utilities. As long as they don’t rely on hacks and instead follow best practices suggested by Microsoft and Lockheed Martin, they will work properly in Prepar3D.
