Upgrading Drupal

With the many recent releases of 5.x I'm a bit behind on updating my sites.

Is it okay to update from 5.2 directly to the latest 5.x version of Drupal?

Or, do it need to update incrementally though each version?

Thanks!

Using Fantastico, I've upgraded 4 installs of Drupal to 5.3. That's the most recent they offer currently.

All the installs went fine, EXCEPT (of course) for the http://delaflamme.org , the most used site. On that site, everything seems to work perfectly well, but ONLY for me when logged in as an admin.

I have upgraded Drupal from 4.7.0 to 5.5. I had installed 4.7 directly under public_html. I have now installed 5.5 in a subdirectory. The site works well.

However, Logs do not show when a new user registers. Also, admin does not receive an e-mail about a new user requesting permission for an account. I am not sure if new user is getting the welcome email. However the account gets created correctly.

..then you may end up with an unusable system. I have about 25 sites, including some pretty high-traffic sites, running in a shared environment on a dedicated box (Ubuntu 6.06LTS, Apache2.0.55, MySql 4.1.15.)

It is not clear to me that the 5.5 upgrade was the entire problem, since I also (stupidly) updated PEAR at the same time) - but, for the last 12 hours all of these sites were oddly 'read-mostly' - the only tables which Drupal could write into were the logs. I was not able to take the sites into maintenance mode, for example, or post comments.

Tonight I did the upgrade from 5.3 to 5.5. This morning I discover that I cannot choose the category while writing a new forum post. The categories are still there (in admin/content/taxonomy). The categories are still shown when calling /forum.
But when I start a new post the dropdown list with die categories of my forums isn’t there.
Did I forget to do something after updating? Can someone verify this?

Wish you all a nice Christmas time! Kind regards - andreas

Drupal 5.5

My host (bluehost) upgraded the server this afternoon and automatically switched to php 5.2.5, you could view my site but couldn't login, they switched me back to 4 and all is okay.

Is there anything I need to do make the site fully functional on php 5?

Apparently there will only be ONE php.ini in the root, whereas before I had one in each domain folder (not sure if this relevant but trying to be thorough).

Thanks
