# [Plugin: W3 Total Cache] Upgrading

 * Does anyone have a suggestion on the preferred upgraded method? I tried the upgrade
   option to do it through wp-admin, but it failed to de-activate plugin, and didn’t
   work. I hate updating the files live on my server, but if that’s the best way,
   I guess I can do that.
 * – Do I need to de-activate the plugin before upgrading it?
    – Do I need to back
   up my config files (running wpmu) before upgrading? – Should I remove the config
   files from the server after backing up? – Should I ‘uninstall’ the plugin and
   then re-install it? – Has anything changed in the advanced-cache.php file?
 * Final question, unrelated to the upgrade. I noticed in the plugin directory, 
   you have a memcached.ini file, with some extra settings, as well as a modifiled
   php.ini file. Are these setting that you are recommending making, or that have
   to be made in order to use W3 total cache effectively?
 * Thanks for the help Frederick! The plugin rocks, and hoping it’s going to help
   us hit some pretty substantial traffic numbers on our hardware.
 * Thanks !

 * > Do I need to de-activate the plugin before upgrading it
 * If you use WP’s upgrade it will deactivate it for you during the process, so 
   yes.
 * > Do I need to back up my config files (running wpmu) before upgrading?
 * The config file format has changed a bit, so you can change it for the purposes
   of manually restoring your settings.
 * > Should I remove the config files from the server after backing up?
 * If you want.
 * > Should I ‘uninstall’ the plugin and then re-install it?
 * See above.
 * > Has anything changed in the advanced-cache.php file?
 * Not that I can recall at the moment.

 * These are just supposed to help you customize your software if you don’t know
   where to begin. They are not required and things will work without the customizations.

 * Thanks for the help ! I tried the automatic upgrade option and it didn’t work.
   Said couldn’t de-activate the plugin, and upgrade failed. Does that mean I need
   to manually deactivate it ?
 * Also, we’re running WPMU, and have separate config files for each site. If the
   config files have changed, and I leave the old ones there, will upgrading the
   plugins replace those config files, or do I need to delete the old ones completely,
   go through the settings panel and allow W3 to recreate the config files?

 * Yes unfortunately until the final release is done, I may have to change things.

 * I would back them up anyway. But try to reuse them if possible.
