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

From 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.

No 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.

With 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 virtual FSX installation, meaning that it will turn an empty folder of your choice into looking like FSX root folder, with all necessary configuration files present. Everything installed there - no matter if by hand or using installers - will appear in Prepar3D.

Virtual FSX installation has numerous work-arounds helping installers and utilities find necessary files. For example: using Migration Tool, owners of EZdok Camera Addon can even get their TrackIR running with Prepar3D.

To avoid conflicts with FSX, should you have it installed, there is a simple user interface to enable and disable virtual FSX with a single click. While it is disabled, FSX addon installers will place files into real FSX. While enabled, FSX addon installers will place files into Prepar3D.

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

Purchased this utility back in 2015 but never gave the developers a review. After many years of great satisfaction with this product I had to give a 5 star rating. This developer continually gives support to future iterations of Prepar3D without asking for an upgrade fee. Because of this product I do not have to wait on most developers to update their products for the newer versions of Prepar3d. One of the best investments I have made in flight Simulation.

How to easily install scenery or plane that only support FSX? Right! Use this tool for it.
I think it has the simplest interface of all times ON/OFF.

I purchased the Migration Tool a long time ago and it has always worked fine with 32bit versions of P3D, which it was designed for.
I not longer use any 32bit simulators.
Migration Tool is not designed for the new 64bit version which is P3Dv4.1, and will destroy your installation if you try to use it with the latest version or if you try migrating 32bit addons to the 64bit environment of P3Dv4.
Migration tool was designed to migrate 32bit addons from FSX to a 32bit version P3D.
Do NOT install any addons into P3Dv4.1 with Migration tool, or any other way, unless the addon developer actually says that it was designed for P3Dv4 or P3Dv4.1.
Sometimes it will work, but most of the time it will break your installation of P3Dv4.
This has been my experience and I believe is a good rule of thumb.

Having similar issues to other users. Causing major problems, and I seem unable to disable or uninstall the software. Support is non-existent, contacted the developer 3 times over the past month and not even the courtesy of a reply to acknowledge receipt or to say they are looking at the problem.

I bought this software to help install Ultimate traffic 2 in P3D. Now I have got a P3D installation that throws up dialogs saying it can't find things. And a FSX installation that is blocked from starting by this software. I will now have to uninstall this rubbish and reinstall my flight sims.And I get to pay for the privilege. Absolute nonsense, don't waste your money!

While you can usually get FSX addons installed into Prepar3D on your own by using junctions, editing the registry etc., this utility saves a huge amount of time by automating the process. It's literally just one click to enable redirection, and one click to disable it. Well worth the cost if you have a large library of older addons.

So let's start writing what this program DONT DO. If you have FSX or FSX SE and you are moving to P3D V3 for example, this program doesn't move all your addons by him self to the new SIM.
So, why is it useful? Well if you try to think that any time that a new patch or version come out, for example FSX SE edition, or P3D V3 and then will be V4 and so on, it need a lot of time for the 3rd parties to change the installer to recognize the new version, and we are not sure they will ever do it... EG. I was using FSX SE edition , bought FSglobal 2010, 80$ product, and when i tried to install it on P3d V3 the installer was not able yet to recognize P3D V3, so what I had to do? Move 24Gb of tecture manually folder by folder? Crazy!! This small little tool is saying to the installer that a version of FSX or even P3D is installed on you pc, but it give the correct path to the installer, so you have just to enable the program, run the 3d party installer and then it will recognize the new path and it works great!!! Without it I would not be able to install tons of airports and free staff in the new SIM. It's true that it doesn't move all the add on staff, you have to uninstall first and then reinstall, but on the other side, without this program I am not sure you would be able to install it at all again. For me it's a Must have for just few money!!!!

This is not a migration tool, it's a tool to help you reinstall your FSX addons into P3D easily. To that extent, it works well. But if you're thinking, like I did, that this will automatically move the dozens (maybe hundreds?) of FSX addons I've installed over the years into P3D at the touch of a button you'll be disappointed. Instead, I'm forced to find and reinstall these items from my download folders, emails, and other places where they've been stashed. Not a pleasant experience, and not what I expected. Maybe if I'd read the copy more thoroughly, or had a review like this to let me know what I was buying, I wouldn't have purchased.

(But if you don't have a problem reinstalling your FSX addons, this tool works perfectly.)

This tool is a Must have if you are running Prepar3D.
I managed to make every single FSX and FS9 Addon work on my Prepar3D
without any workarounds or special configuration.
just run the addon installation as you would normal do with FSX and that tool would automatically
do it's magic and make it install correctly in P3D.
never was I disappointed with this tool.

it's a Must tool and a vital tool for P3D users.!!!

I love it when a product does exactly what the "brochure" says. It's like a Maverick missile: Fire and forget. I used this little gem to migrate tons of add-ons i purchased for FSX in the past years and i'm talking about very complex ones. No problem what so ever. Planes, scenerys, tools, you name it. The ONLY exception is the VRS SuperBug but it is something to do with VRS itself not this product (as stipulated on the VRS support forum).

Money well spent.

Works very well - set it and forget. Haven't come across any issues and makes it simple to move across from FSX to Prepar3d. I got rid of FSX completely, so copying files and changing xml and cfg files isn't really an option, and would have always been a hassle. I've only come across a problem with the Airbus X but everything - from scenery to complex aircraft such as the PMDG 737 ngx and 747-400x seems to install without any intervention. I can recommend just for ease of use.

EZCA and TrackIR installed perfectly into Prepar3D, with this tool. It was so very easy. No modifying file names or XML files. Also installed Carenado's KingAir C90B without any problems and it also works perfectly. I also used the tool to add Arezone's Beechcraft KingAir C90B Soundset to the aircraft. Just read the short manual and follow instructions.
I believe FSX to Prepar3D Migration Tool will be revolutionary in getting flight simmers moved over to Prepar3D from FSX with all of their freeware and payware addons intact.
The support from Flightsim Estonia is great. They are very friendly, answer any questions right away and are constantly improving the tool and adding features to it.

The outside look of the plane is amazing, but the interior of this plane, I would say it's pretty bad. I hope the next update would improve the interior of this plane. Other than that I have no problem.
This is a great app for MFS2020,works great with the crj,thank you for this amazing app.
The more that I use Axis and Ohs, the more I love it. Before using Axis and Ohs, several aircraft had given me a lot of grief trying to get the throttles set up. Aerosoft's products (CRJ and Airbus), Milviz products, such as the KingAir 350i and Piaggio P.180 EVO had me banging my head against the wall because I didn't want to use the default FS profiles without using FSUIPC or something similar. Axis and Ohs have solved that problem! It works with every aircraft that I have used it on, without any problems. It is extremely easy, quick and intuitive to setup. I highly recommend this program for setting up joystick axis and buttons in MSFS, P3D(All) or FSX. For years I've used FSUIPC for axis and buttons. Now, more and more, I'm using Lorby's Axis and Ohs.
Low quality. Particularly bad at night.... Was nice to have at first but now it has been bettered.
Wasn't sure what to expect as I haven't tried any of this developers Scenery before but am pleased with my purchase. Took a bit of a gamble as it doesn't say P3Dv5 compatible and I had to switch off the Orbx Africa mesh which it seems to be incompatible with but apart from that I am more than pleased.
I don't regret I bought it. For me, it's worth my money. I have got a lot of help and support from the developer that's why I give 5 stars and recommend it to others. I am a novice and this program helped me to start an adventure with flying bush trips. Bush trips in principle are not perfect, because you can not adjust the level of difficulty and parameters such as airplane, weather ( I prefer clear skies to see the views ), wind, and time of the day.use drome to look around and Is not possible to use Y-Key (SLEW) to speed up long legs and switch off must to finish the leg before starting the next one. Maybe I would like to start from leg nr.5 ?... -Frank
I have been there flying quite a few times in real life and I tell you, this is good. Every single time I line up that runway or taxi into that ramp I recall the real Sabadell again, the immersion is beyond any expectation. The team behind this must know the airport really well and have been able to put together a very enjoyable scenery. I have also noticed that the blurred textures in new tower are finally corrected after version 1.1.
I am a little bit disappointed with this scenery. Purchased for 3d v5. The surrounding of the airport is very nice but the airport itself is medium quality. Maybe I am expecting more from FSDG but this is my opinion.
Terrible hit to FPS and not that great as lighting, it's easily a 10 to 15 FPS hit to performance, please move on from this product until they fix the performance issues.
Pretty good airport, worth the money in my opinion.
