The workflow is similar but not exact. Also, alternative/miRNA specific tools are available, sometimes on public servers, but also in the Tool Shed https://usegalaxy.org/toolshed if you are running your own Galaxy (cloud, local, docker) https://galaxyproject.github.io/.
You might want to try the domain-specific public Galaxy server Galaxy-CEFAP: https://galaxyproject.org/public-galaxy-servers/
