Upgrade phpBB, upgrade CKeditor, and upgrade/reinstall simpleviewer

I need phpbb upgraded from 2.x to 3.x, and my exisiting template needs to be ported as well. Also, upgrade ckeditor. And, upgrade simpleviewer gallery, if this can't be upgraded, I need the new version installed, and the pictures, etc. ported over. And the template needs to be the same. I may not have all the admin logins for these packages, in that case it will need to be reset with ftp/cpanel/phpMyadmin After the upgrades, I will need to verify it is working how it was before.
