Migration Tool

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 to Prepar3D. Since there are very few differences between the two simulators, almost everything that functioned properly in FSX will function so in Prepar3D.

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 to 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 new and evolving Prepar3D flight simulator.

How does it work?

Migration Tool creates a fake FSX installation, and everything installed there – no matter if by hand or using installers – will appear in Prepar3D instead.

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


Let us give you an example of great addons working in Prepar3D.
