WordPress auto update for core but use local package

Question

I have several local WordPress dev environments but, for the moment, a very very slow internet connection. The WordPress auto updater for core is very convenient, but would it possible for it to use update packages from localhost instead of downloading it for every site?

Answer 1

A list of options, easier ones first.

1. Run WordPress as a multisite network, you can find instructions here: http://codex.wordpress.org/Create_A_Network

2. Manually apply changes via .zip file and overwriting.

   • Download latest zip from wordpress.org
   • Make a backup of your file base per install
   • Unpack the zip files then overwrite files in wp-admin and wp-includes.
   • Overwrite root files but make sure you do not change your wp-config.php settings. It's best to compare the new wp-config for any changes that might have been made so you can apply them.
   • Check wp-content for any new changes and apply them (do not overwrite your existing files)

3. Using Symbolic Links, this isn't easy will probably break stuff.
