Update child theme

It’s OK
Thanks

Hello,
I have a Child Theme
So, if I need to update the Theme I just need to
upload only extracted legenda folder to /wp-content/themes/ folder on my server with overwriting?
whit out changing anything on child?
Because…
On the dashboard I have a Learn more about templates
https://snag.gy/k0gQoe.jpg
The Legenda Child theme contains outdated copies of some of the Vauxhall templates. You may need to update these files to ensure they are compatible with the current version of the Walkers. You can see which files are affected by the System Status page. If in doubt, contact the design kit author.

Do I need to do anything on the child folder?
