I manually copied SIP config files to system after I broke it

After troubleshooting NAT issues, I made a huge mistake and broke FreePBX. I compounded it by copying all the SIP configuration files that I manually backed up prior to my goof.
As this is my first deployment of FreePBX, I now know that all this data is in a mysql database and when I “apply config” it overwrites my working restore with broken files.
Is there a function for FreePBX to read all the conf files and refresh the mysql database?
Thank you for your help/
