Hello Jesus,

> But once changed in the header, What problems can i have. I use domains in all table fields, then changing database dialect and change domains to the correct new values can be done?. I have a very complex database and every time I try to use a pump program for moving data from one database to another hangs.

First you need to learn what exactly has changed between Dialect 1 and 3, and which migration paths are available.

Pick up this download: and read chapter 2 thoroughly. With that, and your knowledge of the database in question, you'll know how to handle the migration. Just don't ever assume that things will go right all by themselves. You *need* to understand what's happening during the migration.
