Upgrading from AC 7.0.X
AC Gold R3 supports upgrading from AC 7.0.6 or 7.0.7 versions. We are planning to add the support to upgrade directly from 7.0.5 in next releases. AC Gold release 1 and R2 supports upgrading from 7.0.7.
To upgrade from AC 7.0.x release to AC Gold follow these steps:
1. Backup your database before upgrade/installation.
2. Upgrade your existing store to AC7.0.7 ( or at lease to AC 7.0.6 if you are upgrading to Gold R3)
3. While installing Gold provide the database details/connection string for your existing AC7.0.7 database, and select the option "This is an existing AC7 database to be upgraded." under "Database Connection" options.
4. Continue with the install and it will upgrade your database for AC Gold version.
