Updating My Current Child Theme To A Newer Version

Hi,

Sorry to be a bother. I use a Themedy child theme on my WordPress site, called Derby, which runs on an old version of Genesis. The Derby theme is old and displays many PHP errors that will break the site soon if I don’t update it to the much newer Derby child theme, which also comes with a Genesis update too. But when I try to update the child theme, all my customisations disappear and the site is poorly laid out, unrecognisable from the earlier Derby child theme. Will this plugin of yours be suitable somehow to help me upgrade to the newer version of my child theme, and keep all my customisations? No customisations were ever done in the parent theme: just the child theme.

Thank you, Stu
