I have a share point website with a list and important records. However my manager told me to amend the columns, as it's type has also to be changed to choice from Azure AD rather than the single line text. I want to know that if I will delete the columns of the form, will it affect or delete the previously saved records? As I don't want to lose the important records of the company.
Matter is urgent and the support will be really appreciated.
Thank you very much.
