Unable to start server as 2025.2 after install update from 2025.1

Hi all, I’m running into issues starting Alteryx Server after upgrading from 2025.1 to 2025.2. We’ve historically upgraded from 2022.2 through 2024.2 and then 2025.1 without issues, but this version is stuck. The logs indicate that the embedded MongoDB service cannot start. Has anyone encountered this or knows a fix?

{"error":"UPGRADE PROBLEM: Found an invalid featureCompatibilityVersion document (ERROR: Location4926900: Invalid featureCompatibilityVersion document in admin.system.version: { _id: \"featureCompatibilityVersion\", version: \"6.0\" }. See https://docs.mongodb.com/master/release-notes/7.0-compatibility/#feature-compatibility. :: caused by :: Invalid feature compatibility version value '6.0'; expected '7.0' or '7.3' or '8.0'. See https://docs.mongodb.com/master/release-notes/7.0-compatibility/#feature-compatibility.). If the current featureCompatibilityVersion is below 7.0, see the documentation on upgrading at https://docs.mongodb.com/master/release-notes/7.0/#upgrade-procedures."}}

Is your Mongo the default Mongo that comes with the designer gallery installs?

Best guess is that the MongoDB version may be incorrect in the ASMongoDBVersion.bin file.

Double check the mongo version using the CLI and make sure its the same version in your bin file.

First manually start Mongo through an elevated CMD Prompt
1. Navigate to the Alteryx\bin directory and enter the following command
2. mongod --dbpath <Path to Database> --auth --port 27018
Leaving the first CMD Prompt window running open a second elevated CMD Prompt window and connect to MongoDB
1. Navigate to the Alteryx\bin directory and enter the following commands
2. Alteryxservice.exe getemongopassword
  1. Copy the Non-Admin Password to paste in the below command
3. mongosh mongodb://localhost:27018/AlteryxGallery -u user -p <Non-Admin Password>

If the versions differ, update the bin file to match and try to start the service again.

Thank you very much for your solution. I’m now able to start the server on version 2025.2.

Before that, I spent quite a long time trying to find the ASMongoDBVersion.bin file. In the end, what I had to do was reinstall the older version (2024.1) to obtain that file. After that, I installed version 2025.1 to update ASMongoDBVersion.bin to MongoDB version 7.xx. Finally, I installed version 2025.2 and upgraded MongoDB using MongoDbUpgrade after installing the server.

Everything is working now.

cheer.

Im glad you were able to get it working! I will say sorry though, because I didnt mention that if the file is missing, you can just create it on your own.

I had a very similar situation happen on my gallery which is why this felt familiar to me. My ASMongoDBVersion.bin is one I created that only contains a version number because mine was corrupt as well

Im sorry you had to go through a lot of hoops, but I am glad you got it working.
