Before the upgrade, make a list of the regions where you currently deploy Oracle Analytics Cloud on Gen 1 and ensure you subscribe to all these regions on Gen 2. For example, if Ashburn is your home region and you created an Oracle Analytics Cloud instance on Gen 1 in Phoenix, you must subscribe to Ashburn (your home region) and the Phoenix region on Gen 2.

      It may take several minutes to activate your tenancy in the new region. See Subscribe to a Region.
