Manual talk:Upgrading to 1.8

Responses to common questions

 * memcached stops working
 * You're using an old version of memcached. Upgrade.


 * MediaWiki namespace stops working
 * Touch the  file to clear caches


 * Can I use a database from 1.8 with an older version, like 1.6?
 * No.

Observations

 * Need an upgrade FAQ for some of the common recurring support questions that can't be covered in the main documentation page
 * Might need to increase the standard protection level to stop well-meaning users from messing up the documentation
