moving a namespace

this method does not update page links!

• assume namespace at A:FOO needs moved to A:B:FOO
• using a terminal, cd into the dokuwiki data directory
• run the following (ignore No such file or directory errors for some commands)

  mv pages/A/FOO/ pages/A/B/
  mv meta/A/FOO/ meta/A/B/
  mv attic/A/FOO/ attic/A/B/
  mv media/A/FOO/ media/A/B/
  mv media_meta/A/FOO/ media_meta/A/B/
  mv media_attic/A/FOO/ media_attic/A/B/

• open and save (touch) the conf/local.php file to invalidate any existing caches
• download and install the Searchindex Manager plugin
• in your web browser, visit the Dokuwiki Admin page
• click the 'Searchindex Manager' link
• click the 'Rebuild Index' button
• manually fix any broken page links

the fact that meta .changes files still reflect the older namespace location do not seem to cause problems, and history, correct authors, and changes all work as expected
