Upgrading Drupal

I recently upgraded my site form 5.7 to 6.2. Because I got soem php errors in the log I installed the Schema module to look for possible database errors.

Below is what schema returns as mismatches.

The differences seem trivial to me? Are there any that need to fixed?. (or should the database be 100% correct?)

Tables for which the schema and database are different.
node

*
node_revisions
o column log:
declared: array('type' => 'text', 'size' => 'big', 'not null' => TRUE)
actual: array('type' => 'text', 'size' => 'big', 'not null' => FALSE)
*
node_type
o column name:
declared: array('type' => 'varchar', 'length' => 255, 'not null' => TRUE, 'default' => '')
actual: array('type' => 'varchar', 'length' => '255', 'not null' => TRUE)

search

*
search_dataset
o column type:
declared: array('type' => 'varchar', 'length' => 16, 'not null' => FALSE)
actual: array('type' => 'varchar', 'length' => '16', 'not null' => FALSE, 'default' => '')
*
search_index
o column type:
declared: array('type' => 'varchar', 'length' => 16, 'not null' => FALSE)

Hey,

I went upgrade one of my older sites today from 5.2 to 5.7. But after I copied the files over, the home page appears blank and when I run upgrade.php there are no upgrade options listed.

So I can't really do anything. Does anyone have any ideas what would cause this?

I am currently running Drupal 5.x, www.JonathanMickles.com on GoDaddy.com and would like to move AND upgrade to Drupal 6.x on Hostmonster.com. Second, I would like to re-theme my site to something similar to http://www.cmslounge.com/drupal5/.

I have been looking on Google and on drupal.org for a long time, but I haven't really found anything that helps me. I am trying to update my Drupal 5.4. to 5.7. before I upgrade to 6.2, just to be sure everything works out fine. When I transfer all the files via ftp, I go to my site, enter the database name, username and password. I then get this error;

We were unable to create a test table on your MySQL database server with the command CREATE TABLE drupal_install_test (id int NULL). MySQL reports the following message: Table 'drupal_install_test' already exists.

I upgrade from Drupal 4.7.6, to Drupal 5.7 now some users cant login. Is like their users doesnt exists. The users table doesnt give me an error after run update.php, and in the logs i dont see something about it. what can be?

Hi, I have just upgraded my drupal installation from 6.1 to 6.2 but now i cannot login to administration to change the status site to online.
Does anyone know where can I act manually on the database in order to change the website status?

thanks,
