Upgrading Drupal

Is it possible to safely update Drupal 7 from BETA3 to RC?
Is the updating path the same as RC to FULL?

I've searched for answers on the forum, but couldn't find any with my keywords.

Thanks for your time :)

This is the first time I am doing an upgrade and I am not a developer so I cannot troubleshoot easily please help this poor woman.

Drupal is installed on the root folder of the server.

I have done the following;
1. I have created a new folder /drupal-6.19
2. I have uploaded drupal-6.19 into the new folder
3. I have copied over .htaccess, misc folder, sites folder, themes module
4. I have changed in /drupal-6.19/sites/default/settings.php $update_free_access = TRUE; to be able to run the update.php
5. I have run /drupal-6.19/update.php

First of all...I need to say, I have ubercart module...after upgrading all modules I have some problem with submit button on cart page. When I click the submit button it redirects me to main catalog page (not to cart/checkout). But if I click checkout in cart_block it goes to checkout page without any mistakes.

Anybody had this problem?

Hi all,
I'm using Drupal 6.19 and the Nitobe theme. Earlier today I realized there was an available update for my theme, so I downloaded it, but now I'm wondering how I can still keep my old styles.css in the new version of Nitobe.
The newest update fixes issues relating to css, so I can't just replace the new styles.css with my old one (otherwise there was no point in updating in the first place), but I made quite a few changes to the styles.css that I wanna keep. There has to be a better way than changing the code again in the new css right?
Hope that makes sense,

Just interested so see if anyone has any tips on this

Cheers

I am running a Drupal based website.

1) Currently, it works with directories rather than subdomains. I wish to convert the existing installation to a sub-domain based drupal installation without losing the contents. How to do so ?

2) After conversion to sud-domain based drupal, I would like to give multiple individual blogs to each users like Wordpress. In wordpress, a user when logged in, at his dashboard, there is an option to create more websites. How to enable that feature?
