Hi,
Please follow these steps:
1. Install the Customizer Reset – Export & Import plugin here: https://wordpress.org/plugins/customizer-reset/, then go to Appearance → Customize: export the current customizer settings,
2. Activate the child theme/parent theme, go to Appearance → Customize: import the file you've exported in step 1.
