I’m sorry if this question is already answered, but it is so specific I don’t believe it is.

I would like to upgrade from version 2.0.4-3 to the latest (2.2.4).

Since I read something about a database update, I would like to know what I must do in order not to lose any information.

In order to not lose any information, you must do regular backups. :o) In order to upgrade your database you run the applicable DB-update scripts that you find in the scripts directory. Since you're talking about 2.0.4-3 I assume you're talking about some distribution-specific package (which may run these DB-update scripts for you), so you probably don't want to upgrade using the source package. What OS are you on? Nils Breunese.
