Problems to update to Enfold 4.5

Hi, i’ve found this procedure in another thred posted by a moderator:

Updating from 4.4.1 to 4.5 via (S)FTP manually works like a charm
However, the steps to get there are quite a lot. Let me describe it step-by-step here:
1) Make a full backup of your website using a backup plugin.
2) Safe the backup somewhere outside from the webserver of your website (e.g. on your local computer or in any cloud storage you trust).
3) Sign out from your WordPress website.
4) Go to your themeforest account, sign in and download the updated Enfold v4.5 to your computer. Extract it and search for the file enfold.zip. Extract this file as well to already have your folder ready to be uploaded.
5) Sign in to FTP or SFTP using FileZilla or any other tool which is able to do that.
6) Go to the folder ./wp-content/themes and search for “enfold”. If you want, you can download the enfold folder to your computer as well (just in case you want to restore if afterwards which is easier like that than using the whole backup).
7) Delete the folder enfold via FTP. This may take 5-10min, depending on the server speed obviously.
8) Wait until it is finished and the enfold folder is gone. If that is the case, upload the “new” enfold folder including v4.5 to your website in the same directory.
9) Sign in to your WordPress website again and go to the Enfold tab (or the one from your child theme). Scroll down to the tab called Theme Update.
10) Your current API token will not work anymore as Envato changed some stuff on their API. Therefore you need to remove your current key and generate a new private key as visible in your themeforest account under “Settings” -> “API keys”. Go to https://build.envato.com and follow the steps there. To me, https://kriesi.at/documentation/enfold/(Purchase code hidden if logged out) /#toggle-id-5 was also very helpful (scroll down a bit there to find out about the permissions your private API key needs in order to check for future Enfold updates). Without these permissions it will not work.
11) After revalidating your new private key within the Enfold update tab, you should see a blue rectangle saying when it could be checked for the last time.
12) Done!
I hope this helps anybody who has/had issues with updating Enfold to version 4.5.
Feel free to ask me in case you need any assistance.

My question is:
considering that i’m using an Enfold child theme, is this procedure still right?
If yes, I have to apply this procedure only to the “Enfold” folder and not to the “Enfold child”, right?
Thanks
