Upgrading Drupal

I had bunch of Unicode (Russian/Ukrainian)-containing data entries in my MySQL database in Drupal-4.6-based site. Now, if I dump that data from old database and and load it into Drupal 5.1 database from command line, the resulting strings are shown in a browzer as garbage.
Can someone point me to code/changelogs about the change that happened, and what utility shoud I use to upgrade my MySQL data?
Using standard Drupal's update.php is not an option for me: my codebase is too much modified for my needs.

Hey all.

I ran into this, I have a feeling it's something simple, but I can't find a post that answers my question yet. I am in the process of upgrading, just made a test site. I got everything working on it except for my clean URLs. It's a pain to make sure everything works manually!

I did indeed copy over the .htaccess file. I know mod rewrite is enabled because I have the clean URLs working fine on the public site. I do not have root and cannot access httpd.conf.

We're in the middle of an upgrade from 4.6 to 5.1.

We've been doing the upgrade on a snapshot from about 2 months ago.

Next we're skinning the site with a completely new design.

We're also trying to plan the deployment to the live site.

What's the best way to put the new skin and database structure into production with the live data?

Do we have to take the site down and "start over" on the version-wise upgrade?

How have others done it?

Thanks

Greetings,

I just upgraded to v 5.1 and am now unable to edit primary or secondary links. In all themes the boxes (Engine-specific settings) to edit the links do NOT show up under the themes page: for instance http://www.example.com/admin/build/themes/settings/fancy

I just upgraded a site from 4.6 to 4.7 and I'm having problem with the search feature. The site is indexed and the search function from this page is working:

http://www.menno.org.uk/search/node/library

But typing search terms into the box on the sidebar does not bring up any results, even when the search from the main search page above does.

A cursory search through the forum archives here didn't turn up the same problem anywhere else. Any suggestions?

Thanks in advance
