Upgrading Drupal

I attempted to upgrade from 7 to 7.4 and did not see any errors. Now when I look at the home screen, I see the following error:

FastCGI Error
The FastCGI Handler was unable to process the request.
--------------------------------------------------------------------------------

Error Details:
•The FastCGI process exited unexpectedly
•Error Number: -1073741819 (0xc0000005).
•Error Description: Unknown Error

HTTP Error 500 - Server Error.
Internet Information Services (IIS)

Does anyone know how to resolve this issue?

I am running a Drupal 7.0 installation on a Bitnami image on Amazon EC2.

This may sound stupid, but I can't find a link that gives me the steps to upgrade an existing Drupal installation. I downloaded 7.4 and the INSTALL.txt file has the following sections:

I have a Drupal 7.0 site using SQlite for the database. After I upgraded to 7.4, I received this error:

PDOException: SQLSTATE[HY000]: General error: 8 attempt to write a readonly database: DELETE FROM {flood} WHERE (event = :db_condition_placeholder_0) AND (identifier = :db_condition_placeholder_1) ; Array ( [:db_condition_placeholder_0] => failed_login_attempt_user [:db_condition_placeholder_1] => 1-74.128.149.251 ) in flood_clear_event() (line 1167 of /var/www/html/includes/common.inc).

I am trying to upgrade our community website from 6 to 7 but I am stomped at this error:

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'venuspri_alsanaty7.blocked_ips' doesn't exist: SELECT 1 FROM {blocked_ips} WHERE ip = :ip; Array ( [:ip] => 204.15.64.69 ) in drupal_is_denied() (line 1657 of /home1/venuspri/public_html/alsanaty7/includes/bootstrap.inc

How can we fix this?

I did an upgrade from 6.22 to 7.4 and it didn't turn out too well. A lot of 7.x modules aren't working, forum is broken due to taxonomy issues, and a number of other errors pop up whenever I try to fix something.

I plan on doing a fresh install of 7.4, but need to migrate all my users and forum. Do I need modules to do this, or can I just grab certain tables and import them directly in the database?

Any help is greatly appreciated. Thanks!

I came across an old comment from 2009 asking for upgrade instructions in the release notes . This is still not happening (eg http://drupal.org/node/1204634).

Please, if you want to make Drupal earier for us newbies, then you need to make the simple stuff easier. Right now it's an absolute pain to find out anything basic about actually using Drupal in practice.
