#Use phpmyadmin to backup all of the wiki tables!
#Locate all pages on the wiki that have 3.x in the title - from the wiki: toolbox, Special pages, All pages to get a full list of wiki pages.
#Copy/paste it into text processor - it
is in three columns separated by tabs. Use regular expression search/replace to replace tabs with carriage returns. Using GEDIT, best to replace <code>\t</code> with <code>\n</code> rather than <code>\r</code>. You now have a list of all files on the wiki, one title per line. Save it as a text file (I'll call it <code>myfile.txt</code> for this example).
#Use grep to find only the pages with <code>3.x</code> in the title: ''<code>grep "3\.x" myfile.txt > mynewfile.txt</code>'' The backslash will make the full stop a literal rather than trying to be part of a regular expression.
#Use a text editor to view the new file, and delete any pages that you don't want to roll over (That is, some pages may refer to <code>3.x</code> in the title, but are not pages that we want duplicated into <code>3.z</code>...)
