Upgrading Drupal

Does RC2 have any differences in the database, admin or require changes to modules?

I switched from RC1 to RC2 by dumping RC2 over RC1, copying some database settings from the old settings.inc to the new settings.inc and then running update.php. Update.php did not report any changes. I am wondering if there were any changes to the way the data is used?

During quick look through the admin section I did not spot any changes. The changelog suggested RC2 has only minor code changes that do not create any new functions or settings.

I address to this forum because is my situation now (post-upgrading) and because always I have had a daily response of my claims and questions. Ahhh solving my problem.

I tried to upgrade from 4.6.6 an get the following messages (this is only a part of them)

Warning: Unknown column 'referer' in 'field list' query: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (1, 'php', 'Table 'db0508101.node_revisions' doesn't exist\nquery: SELECT n.nid, n.vid, n.type, n.status, n.created, n.changed, n.comment, n.promote, n.moderate, n.sticky, r.timestamp AS revision_timestamp, r.title, r.body, r.teaser, r.log, r.format, u.uid, u.name, u.picture, u.data FROM node n INNER JOIN users u ON u.uid = n.uid INNER JOIN node_revisions r ON r.vid = n.vid WHERE n.nid = 2 in W:\\www\\includes\\database.mysql.inc in Zeile 120.', 2, '', '/', '', '127.0.0.1', 1144262615) in W:\www\includes\database.mysql.inc on line 120

After reading Upgrading your site without a DB upgrade, I wanted to find a solution that didn't require uploading the whole 4.6.6 site and figuring out which customized files I needed to carry over from my 4.6.5 install. But after reading a bunch of posts and handbook pages about applying patches, I wasn't too enthusiastic about going the patch route either.

I know many programs have problems upgrading between versions, since they completely reformat the database layout.

My question is: is it safe to upgrade from version 4.6 to 4.7? Or will it mess up my site? I have about 1900 nodes made so far, and I don't want to have to manually recreate them.

Hi,

I have tried to restore a Drupal phpmyadmin backup in a new hosting, but I find this error
