As Bart points out, there are no migration tools. However, there are some strategies you can take to minimize the effort.
- First, you should be able to extract key information such as credentials, ports, etc. that are required to configure monitoring of technologies that can't be auto-instrumented. Then, reuse those with Instana. The Instana install process can be easily automated via Ansible, etc. and tied into Git for configuration. The main thing to keep in mind when installing the agents is that observability solutions won't coexist nicely on the same systems. So, you'll need to stop or uninstall Datadog before installing Instana.
- Things like thresholds can be created via REST APIs
