Dear Support team 
I have Purchased PenNew Wordpress theme, I will install it on my website and replace it with Cheerup Theme
My website : www.arriveturkey.com 
What is the correct way to replace the theme, is there are any advice from your side so i won't lose my articles, categories or having any problem later? 

or should I install it and activated normally? 

Best regards

Hello, Thank you so much 

For the last question, i have moved my theme without any problem

I just have another questions as I'm trying to find the answer before bothering you guys, I know how many message you are receiving and have to answer :D 

A: In my tap : Add More Google Fonts To Select Options of Fonts

I don't know  how to add the fonts, I can not select a font ( theres no such option) at the attachment.

B: How i can remove the fonts Im not using at my website so it will increase the performance of my website?

C: when Im checking my website performance on Google light house, unused CSS and JS is effecting my speed score, is there is a way which i can cancel these files? 
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. 

Thank you for answer but in the font option it doesn't appear as a drop down menu, It appear like a list without selection as it shows on the photo i attached
