Urgent help! Changing a field type from 'Single Line' to 'Import Data'- will I lose previous entries?

Hi everyone,

I'd like to take advantage of the new search and auto-complete function in creator. I have a 'Single Line' field that I'd like to change to an 'Import Data' field.

Will I lose the data from previous form entries if I do this???

Thanks!
