change of domain name

Hi,
my client decided he wanted me to change the principal domain name from fateline.co.uk to not-another-datingsite.com. They both have an SSL certificate. They both have the premium plugin. I now notice that profile pictures no longer get displayed. Can you advise what changes i should make due to the domain change. I suspect it will require me to edit the database which i’m ok with how to do, it would just make it easier if you can list the database table name(s) and any columns which i should focus on. Plus anything else e.g. changes to the theme configuration. Many thanks, nigel
