I am having trouble doing a straight upgrade and have been unsuccessful in upgrading my 2.1 install.

A question. Could I install 2.2 new copy. Then run the install etc.

Then run the upgrade scripts 2.1 to 2.2 on the 2.1 Existing database and modify the settings file so my new 2.2 install could look at the data converted through the scripts to 2.2 and run?

Any suggestions since we need to upgrade to the new version because of speed and have not been able to.
