Upgrading Drupal

I've inherited control of a website running Drupal v7.4 and noticed right away that it wants to be upgraded to v7.23. This seems like a pretty extreme upgrade, skipping over 19 intervening versions of Drupal. Is this even possible to do in one step? Or do I need to do it one version at a time (which seems like it would take hours)? I've never attempted an upgrade that was more than one version number more advanced, so any advice on this would be helpful. Thanks!

Hi,

We have about 15 sites in a dedicated server. two of them are drupal, we have a problem on them, when we want to clear cache or run heavy scripts they take too long about 7-8 minutes or more, I restore these sites on other shared host and these scripts run less than 40 seconds,,,where is the problem?

Thanks and regards,

Hi there,

I am new to drupal and have set up a prototype site for a client..I am using google doc viewer and am having some quality issues with images

see http://aquia.rmssseniors.org/content/pitt-medows-news-flash for a bit of a view this is a.doc file
it has a number of images so be patient you will see the images are relatively poor quality pdf,.doc seem to be the same quality
There are different resolution and images resized .... in the document

I'm upgrading from Drupal 6 to Drupal 7.23. I think I did everything as described in UPGRADE.txt. When I rum update.php as described in Step 14 I get following error-message:

Hello,

I have upgraded a site from D5 to D7. First convert from D5->D6 and than D6->D7.

When I looked at the Data Base I noticed dozens of "garbage" tables that do not belong to D7.

is there any way to delete D5 & D6 tables from database?

Thanks
