What happens to the changes made to the standard OTR texts in E-recruitment

Hi all,

I have to change the <b>OTR texts of e-recruitment</b>. But I doubt whether they remain changed or overwritten in upgrade if I directly change the OTR text itself.

Any one please help me in this issue.

If I want to keep the changes in upgrade how should I proceed.

Thanks in advance.
