I came across this post, with a self explanatory title – “13 Most Important Things to do When Changing the Wordpress Theme“. This is particularly relevant to me, since I am updating my theme right this moment. And so, I thought, I’d just revisit the list items of that post with my own comments, since they are so fresh.
Take a backup of your current theme folder. That is always a good advice. Better even, take full backup of your blog, including the database dump. Why is the dump relevant for theme upgrade? No, not because I am obsessed with backups now that I lost all my archives. But because most themes these days include dynamic sidebars, which you usually fill with widgets. Widgets configuration is kept in the database. And when you are moving to a new theme, your dynamic sidebars often get out of sync, and you try to fix it fast by re-arranging widgets again. In case things go very wrong, it’ll help to have a database dump as well, which, when restored, will bring back your widget configuration.
