Extra in Dashboard

Dashboard image

My current theme is a custom one of an previous employee. As of right now I don’t communication with him. I am looking to replace the theme with Professional, a WP created theme. When I switch the themes, I loose the two items that are in the red box. How can I move/transfer that data from those two to the new theme.

I’m not a pro user in WP but I can find my way around ok.

The whole purpose to me switching is because I am not add any more items to the menu. I have tried changing the php.ini file but I had no luck.
