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.

Not so bad, but clearly don't worth the price for which it's sold ! At least, the author could have done some research to include the tower frequency. Not everybody can't use ADE to fix this. Also, compared to a new airport in the same area (FSDG Lite Dakar - GOBD), this last one is a bit better for the half of the price ! I had choosen this airport to try once a FSXCENERY product, but it will also be the last time until they find a correct balance between quality and price !
This really adds depth to the sim. My only issue is with some of the colours in the Caribbean. Too much of a purplish colour in some areas (Trinidad) and some trees are too brown, but great overall trees, textures & LOD.
Not bad but the ramp is sloppy. The markings around the jetways need a lot of work.
This is the third Aerosoft scenery P3DV4.5+ scenery from a talented developer Pavel Moroz and I must say is one of the best provided with the complexity and details. I also own LZKZ Kosice and LZTT Poprad Tatry which are very good quality too. Stefanik LZIB airport is modeled with all the details and corresponding to reality. A big surprise was for me how is the city of Bratislava modeled with many of detailed buildings and it reflects the big development boom, so this very big plus. Some big texture will need optimization in some complex buildings but I am sure the author will do that in the next update. I am pretty sure that we will see this complex scenery in MSFS2020 too and expecting new airports in the surrounding area.
gret scenery worth every penny and you get the city as well we need somethin in ukraine now
Very cool Kremlin! By the way, I found Russian cars on the territory of the Kremlin and a tank!
Loved the statue and the stadium! This is a great city! A city of military glory!
Many different buildings and great night lighting!
Flew by this last night on a terrain LOD 9 looks so good!!!! The night lighting is awesome!!! can see this from way, way back
