Implications When You Change Data Warehouse Locations
When you change the location of the data warehouse from North America to Europe or Europe to North America, the data that your reports use changes. Because Secure Access' reports use the data saved to logs that are stored to the data warehouse, only data from the data warehouse's current location is available to reports. Existing logs do not change locations. Data stored in North America stays in North America. Data stored in Europe stays in Europe. To generate reports using data from the previous data warehouse location, you must change the data warehouse location back to the previous location.

Although you can change back from the European data warehouse location to the North American data warehouse location, we do not recommend this procedure. Changing back and forth between data warehouse locations results in the splitting of your Secure Access event data between locations. This splitting lessens the accuracy of your Secure Access reports. We strongly recommend that once you change the location of your data warehouse from North America to Europe that you do not change back unless the change back is intended to be permanent.

When you change the data warehouse's location, Secure Access' reporting functionality is temporarily suspended while the switchover to a new location occurs. For activity search data, the switchover period lasts only a few minutes; however, other reporting data may take several hours to begin appearing in reports.
