Hi Balaji,
Feel free to connect directly (bruno.costa@infosistema.com) if you'd like a demo of DMM, a trial license to test/validate it or clarification on the subscription process.
We also have a distribution partnership program that I think could be interesting for you / your company.
DMM has some free features (data import from legacy, data anonymization), when you install from the Forge you get 5 free executions (with some limitations), and for that data migration (onprem->Cloud PaaS) you will need a valid subscription license.
Hope to hear from you soon!
