Hi
I have been on salesforce for more than 5 years and i have handled many data migrations to/from salesforce.
Example : Runbooks info to salesforce, Quickbooks info to salesforce, Twilio to salesforce.
In specific to this requirement, I have worked on Twilio to SFDC integration to implement a SMS survey initiated from mobile.
Further we can discuss upon contact.
Thanks
