You will need incremental upgrades for your wordpress since you are using old version. All your data should remain intact and you should not require to redo everything.
Before you start upgrading, make sure that the theme which you are currently using is compatible with latest version.
Finally, do not forget to take complete backup (web contents and database) of your existing wordpress.

Once I back everything up, where do I go to get those incremental upgrades? Are they free? Is there a lot of work involved, or is it pretty easy/automated?
Thanks!!!

here’s a related post. Gives upgrade order that is generally agreed upon. Plus a link to archive WP downloads
Not automated until about the last one or two jumps.
The manual guide looks worse than it really is – scared the daylights out of me the first time – I had lots of Highlighter marks on the printed page. Once I figured out that there were a few files that were saved from one version to the next and not replaced and there are some directories that also remain the same from one to another.
I had to upgrade right out of the blocks as my host had a real old install that would not run the theme I wanted.
Print the instructions and make notes ahead of time (or at least I needed to)
Keep the faith and there are a lot of great folks in the forum that will help if you have problems or questions.
