We have a requirement to change the type of one the field from Integer to Text f

Thank you Abhi, Your advice resolved the new functionality and process variable issues to UI.
We are facing another issue which we are yet to resolve,
Issue: 1. When we deployed the application from DEV to Test with the changes in existing CDT's, the application failed to deploy with error log attached.
2. So we deleted the Existing old CDT's from Test Environment and redeployed the application again, which in turn resolved the deployment issue.
3. Running Processes in the TEST started using the older version of CDT's with "^version" (EX: Root as Root^1).
4. Process upgrade smart service is not handling the CDT changes with ^ versions.
All these CDT's are consumed by the Webservices, So the option of changing the Name of CDT's is not viable for us.
Please advice,
thank you
