Upgrading Drupal

Im attempting to upgrade a 4.6.5 installation to 4.7.0...

I uninstalled all contributed modules and themes, and removed the old files and installed the new files. Once the files were in place I ran the update.php script, my first attempt I recieve the error:

user warning: Duplicate column name 'severity' query: ALTER TABLE watchdog ADD severity tinyint(3) unsigned NOT NULL default '0' in /var/www/html/drupaltestsb/includes/database.mysql.inc on line 120.

Hi I am just wondering if I ought to upgrade from 4.7rc4 to 4.7.0 the official release or are they the same?

HI all.

I just finished upgrading two sites (running off the same drupal code base), and things went pretty smoothly. If you're thinking of upgrading, make sure to watch the 4.6 -> 4.7 upgrade video...EXCELLENT! (http://drupal.org/videocasts/upgrading-to-4.7)

I have a few minor questions/problems.

1) I can't get the TinyMCE editor working anymore. I installed Drupal 4.7 in a different directory than where Drupal 4.6 was, and downloaded and installed the TinyMCE module for Drupal 4.7, enabled it, but I just get the default Drupal text area. (Yes, I downloaded and installed TinyMCE into the new 4.7 directltory and yes, it's enabled. :-)

2) How often should the update.php script be run? I ask because when you first run the update.php script to do the update, it specifically indicates not to run the update.php script more than once. However, click on Administer-->Modules, and just above the list of modules, it says "It is important that update.php is run every time a module is updated to a newer version." Ex. I was using the bookreview module in 4.6, disabled the module for the upgrade, then downloaded and installed the 4.7 version of the module for Drupal 4.7. I then enabled the bookreview module. Should I be running the update.php script again now, because of the new bookreview module?

3) After the update, I have "edit secondary links" and "edit primary links" links at the top of my page on one of the sites. Clicking on either one returns a "page not found". I know that there was a spot to edit the primary and secondary links in Drupal 4.6, but I can't seem to find it in Drupal 4.7. Where did it go? Or did it just go away?

After updating to 4.7 (and getting updated modules) I get an interesting variety of errors constantly.

array_keys(): The first argument should be an array in /usr/shared/web/caseyj/edu/modules/user.module on line 348.

implode(): Bad arguments. in /usr/shared/web/caseyj/edu/modules/user.module on line 348.

I guess the title says it all... :)

I was using version 4.6 and recently got a new domain and a fresh install of version 4.7.

My Google ads were showing up perfectly when I pasted the code into Administer, Settings, Footer Message in 4.6. When I copied the exact same code into in 4.7 with Administer, Settings, General Settings, Footer Message, my text shows up but the Google Ads don't.

Used the update from 4.6.5, no errors reported, but now no content appears (just "n/a"), and admin/block shows the correct list, but checking has no effect; they can't be enabled.

The errors that appear:
Message Unknown column 'sid' in 'field list' query: INSERT INTO accesslog (title, path, url, hostname, uid, sid, timer, timestamp) values('...
