# Upgrade Tests This tool can be used to test DB upgrades between two Fleet versions. To run the tests, you need to specify the "from" and "to" versions, for example: ```sh FLEET_VERSION_A=v4.16.0 FLEET_VERSION_B=v4.18.0 go test ./test/upgrade ``` Ensure that Docker is installed with Compose V2. To check if you have the correct version, run the following command ```sh docker compose version Docker Compose version v2.6.0 ```
