Updating Wordpress

[MightyMike]

Hi,

I have a mainstream blog which is running WordPress 3.2.1 on a custom theme, and i want to update it to WordPress 3.3.2. will it screw up the theme do you think??

First, make a backup of files and database, then update WordPress.

It will not break your theme for sure, but you are safer this way

As OriginalEXE said, and it is very recommended to update to the latest WordPress version (plugins too) for security issues.
Do a backup of your blog (Tools -> Export -> All content) and do a backup of the files that sit on your host site. every time you do a change to your content save a new backup.

No it won't screw up the theme.
