Can we put all code of Google tools with Google Tag Manager tools code?

Hi Friends,

My site already configured with Google analytics tools code, Adwords tool and Webmaster central tool, Can we implement Google Tag manger without affecting Google Analytics data and webmaster tool. Or we just put one code of Google Tag Manager. Actually I don’t want to lose our Google Analytics data. Can anyone have solutions with resource URL, kindly share with us?

Thanks in Advance.
