You'll want to do a schema only dump of your current database any load that into the 8.1 database. Once you feel comfortable that this works ok, try a data only dump and load that into the 8.1 server. Once you comfortable all that works, you're ready to upgrade. I will note that if you're planning to upgrade, I'd recommend going stright to 8.3. 8.1 is a few years old, and 8.3 provides a number of features and improvement you'll benefit from. Unless you have a strong reason to do otherwise, go to 8.3.
