Save 'Profile fields' and 'Profile field groups' to push to different environments

I wonder if somebody can help with the following:

I have done an update to the Profile page which includes adding new 'Profile fields' and 'Profile field groups', and I have made the relevant changes to the profile page default and I can see the changes are saved as default within the XML stored in the 'factorydefaultconfigurations' folder.

I need to push these changes to the UAT environment. however, the profile page doesn't contain the new fields/groups.

None of the new profile fields and groups exist within UAT. Are these stored in a specific folder for me to push up the environments?

Thanks in advance
