What's the correct and easiest way for upgrading versions without losing existing data?
We've added fields to some tables and modified some stored procedures for linking orders and users data to an external database, and losing all what has been made isn't an option.
We created a parallel installation in IIS7 for 2.5003 and tried connecting it to the existing database, by changing the connection string in web.config, but with no avail because it keeps firing up the installation wizard. How can we make the connection without using the wizard?
Do you have a comparative table of what changed from 2.0002 to 2.5003 database wise?
Thanks
