1. Before you change, edit all the new theme. Have the new theme definitely ready and all functions and options well organized and running smoothly. Of course, much is published after already launching the issue, but try to edit the maximum and all you can, when really you do the exchange, the store was disorganized quickly.

2. Back up your entire blog. Arthème to switch to the layout of the blog has some weird settings (not have the theme) and had to return to innovate. So, first of all create a backup, not to off then. You can use the WP-DB-Backup to make this work.

3. Test plugins you used before to see if all will work in the new issue.

4. Read the explanation page of the theme. So you can hear some settings that do not know “and studying” and updates the request of some readers, that sometimes are only available in the comments. This page is usually in the blog of who provided the theme.

5. Test the new theme and see if it runs in the major browsers available. The Browsershots does this work for you.

6. If the new theme has a problem that you have not managed to resolve, try contacting the creator of the template to take your questions.

7. Keep at least the color palette of the theme before. Try not to drastically change the layout of a blog for your visitors are not “lost.” The visual identity of your blog is very strong, and there are frequent cases of people who had a lower rate of visits to a theme change.

8. Ask someone to give a supervised in your new template, before releasing it. A view “from outside” can point to many errors that go unnoticed by those who are editing the theme.

Taking these precautions, you avoid many mistakes that can really stress you, to take more than your time.
