 * Hi there,
 * What should I expect upgrading WordPress from version 2.9.1 to the current (3.5.1),
   if the theme is old and haven’t bee updated – my client is using that one – [http://wordpress.org/extend/themes/unspeakabledogness](http://wordpress.org/extend/themes/unspeakabledogness).
 * What should I expect to encounter ? How can I check the level of compatibility
   before updating ?
 * Thanks,
    Amit

 * chances are your theme will break.
 * You may have to use a new theme, particularly when you already know your theme
   is pretty old and its not being updated!
