Upgrading Drupal

I have installed several -dev versions on my site, and would like to update to a newer -dev version. But how can I do this? The update manager only suggests "green" releases for update, even if these are months-old alpha releases. When I try to install the newer -dev package through "/admin/reports/updates/install", I get an error that this module is already installed. AFAIK, I can't uninstall the old dev package without data loss either, because its database tables will be deleted, and possibly other uninstall operations executed.

So how can I update?

I fear I've done a huge 'School Boy Error'

I simply copied and pasted everything from my FTP on Drupal 6 onto my desktop, and moved the new Drupal 7 downloaded files over into the existing folder.

When I ran the update.php page, it doesn't work..... doesnt exist.

If I go to my website

www.lafunks.com/drupal

Can anyone help?? I would be most appreciative of any advice

I see this :-

I get redirected to /op=info whenever I try to access /update.php after I upgraded to drupal 6.20. I've enabled debug logging in apache and there is nothing on the error.log file. In the access.log file, I get this:

hi,

i added the Nice menus module to my working installation. I also enabled Menu Trails. Did an update. Suddenly, i can't see the links on the admin page because i'm getting a "do not have any administrative items" error.

I've reviewed this thread:
http://drupal.org/node/250728

I un-enabled the two menu modules. I also moved them out of the modules directory. I ran update.php and chron.php. i still have the error message.

I used a script to rebuild my menu tables:

  require_once './includes/bootstrap.inc';
  drupal_bootstrap(DRUPAL_BOOTSTRAP_FULL);
  menu_rebuild();

(the script is named index_rebuild_menu.php.) Same result, i still don't have any administrative items.

i have looked at the menu_links table via phpMyAdmin:
SELECT *
FROM menu_links
WHERE link_path = 'admin'
AND module = 'system'
LIMIT 0 , 30

following suggestion offered by ebw on the above-referenced thread, i saw this statement:
Resetting the values of mlid and p1 to '2' resulted in a return to the prior (correct) display. (ebw)

When i attempt to change mlid and p1 on the database record for the link_path=admin and module=system i get this error:

update {MyDatabase}.`menu_links` SET `mlid` = '2',
`plid` = '2' WHERE `menu_links`.`mlid` =3

MySQL said: #1062 - Duplicate entry '2' for key 'PRIMARY'

I tried following the installation documentation to setup a multisite from cpanel, but it doesn't work. The 2nd site tries to connect but never does.

5 minute multisite using Cpanel

You want petermoulding.biz, cjm.net.au, and unlevelhome.com on the same server, or virtual private server, using one copy of Drupal and a separate database for each site. You are using Cpanel. The first site will take whatever time you need to upload and install Drupal. The second and subsequent sites will take 5 minutes each. This example uses Drupal 6. Drupal 7 appears to be the same.
First site
I assume you have the first site set up. You used WHM to create a database account for petermoulding.biz then went into Cpanel for petermoulding.biz to set up email and install Drupal. You now have petermoulding.biz working with Drupal 6.
When you created petermoulding.biz, you created a user for the account and I will assume the user is named pb. Use the MySQL Databases option or the wizard. I use the MySQL Databases option. You create a database named drupal and cpanel shows a database named pb_drupal. You create a user named drupal for the database and Cpanel displays user pb_drupal. You then connect user pb_drupal to database pb_drupal with all privileges.

Hi-

I've inherited an actively-used Drupal site that has not been maintained since 2006. The current version is 4.7.4. I'd like to upgrade it to 6 or 7.

I see advice to make all minor upgrades, then the major ones. But I can't find where to get the 'latest' 4.x or any 5 versions.

Does anyone have advice about how to proceed? The site seems to be fairly stock, using core plus the following modules: captcha, ecommerce, event, flexinode, inline and simple_access. Given all the material that's online, I'd much rather upgrade than try to install from scratch!
