You said you are using office 365 so it would be the office 365 records.
What I suggest you do is goto https://dcc.godaddy.com/manage/YOURDOMAIN.com/dns
replacing YOURDOMAIN.com with your actual domain. This will show you the current domain settings you will need to copy to the new DNS servers.
If this is not something you feel comfortable with I suggest speaking with an IT consultant who can help you set this up.
