Hi all,

I need to migrate my WordPress site to a new server as I am no longer able to upgrade the old one because the latest version of PHP is no longer supported on the OS and I can’t upgrade to the 5.x versions of WP.

I am migrating from Windows Server 2012 to Windows Server 2019, using Platform Installer.
I’ve got WordPress installed, but it is version 4.9. I want to use the WP automatic updater to update it to the latest 5.2.2 version. However, I am getting the following error:
——————-
Update WordPress

Downloading update from https://downloads.wordpress.org/release/wordpress-5.2.2-no-content.zip…

The authenticity of wordpress-5.2.2-no-content.zip could not be verified as no signature was found.

Unpacking the update…

The update cannot be installed because we will be unable to copy some files. This is usually due to inconsistent file permissions.: wp-admin/includes/update-core.php

Installation Failed
—————-

I have direct access to the server, so I have tried to set folder permissions to write via Windows Explorer, but it doesn’t seem to stick, when I go back to check it reverts to read-only. Any advice would be appreciated.
