Here’s everything you need to do:
On the computer that has the Chrome profiles that you want to retain:
Copy the “User Data” folder found in this path to portable media: C:\Users\%username%\AppData\Local\Google\Chrome\
Export this registry key to the same portable media: [HKEY_CURRENT_USER\Software\Google\Chrome\PreferenceMACs]
Move the portable media to your new computer.
On the computer that you want to move the Chrome profiles to:
Make sure all Chrome browser windows are closed and chrome.exe is not running
Copy the “User Data” folder from your portable media to C:\Users\%username%\AppData\Local\Google\Chrome\
Double-click the registry key that you saved to portable media in step 2
Open Chrome, and you’ll find your profiles are present!
