Replace daughter-board to fix broken charging port?

Hi, my mom has a Nexus 7 2nd gen tablet and the charging port is broken. Sense that is a common problem it looks like i am wanting to fix it. my options are a Micro soldering job or replacing the daughter board that it is on. I want to go with the Daughter board replacement as that would be cheaper and easier plus i can change it my self easily. one question Is there anything that i need to watch out for while doing this?
