Upgrading Drupal

I updated last night and now I get this message:

Hi,

We are currently running Drupal 6.1 with MySQl 5.1. I need to upgrade the MySQL to 5.5 for security reasons. However, I will leave Drupal at version 6.1. Will this combination work?

Also, what should I be aware of when doing a database upgrade like this? Besides backup the DBs, etc..Do I need to update the Drupal config, etc?

Thanks.

Tom

Hello Drupal,

I recently been put incharge of a drupal site. I have viewn our updates page and see that our core is out of date as well as some of our plugin's.

Why can I not upgrade the core?
Is there an update log for the updates? Do I risk messing things up by updating plugins?

Thankyou,
Mike

I updated my site from 7.12 to 7.17 and the update has complete successfully, but now when I try to access to site I get a timeout error all the time:

Fatal error: Maximum execution time of 30 seconds exceeded in path\to\drupal\includes\database\database.inc on line 2139

What happens?

Thanks.

I upgraded Drupal from 6.x to 7.x some tiume ago, and have been grappling with this issue for some time:

This is my method - something is wrong with it, looking for help;

1. D6 version of site work fine at mydomain.com
2. D7 dev version of site works fine at new.mydomain.com (a folder under root of mydomain.com - mydomain.com/new ).

To go live with new D7 site, I thought I would do this so as not to have to FTP:

A. Put both sites into maintenance mode.
B. Copied the D6 site files into a folder I created in root of mydomain.com called _BACKUP
C. Copied the D7 site files from the 'new' folder into the root of mydomain.com.
