In the next few months, AppDynamics will be migrating customers on controllers in the AppDynamics Datacenter to our new Americas Datacenter. This notice serves to share details and benefits of this plan.
Controller migration benefits:
Faster time to features
Zero downtime upgrades — you will continue to receive maintenance notifications when we migrate, but you will not notice any downtime in the UI and no metrics will be lost during maintenance. (Note that all UI sessions expire during the maintenance event).
Improved scaling capabilities — when needed, your controller capacity will be increased without any downtime
Improved HA capabilities — new database architecture that performs multiple writes to multiple copies
Improved DR capabilities
Customers who have IP whitelisting or other outbound IP traffic restrictions in place will need to whitelist a new set of IP addresses in addition to the current ranges by February 28, 2020. New IP addresses will be provided starting November 4, 2019.
To minimize the downtime required for the maintenance and ensure this one-time maintenance process runs smoothly, access to snapshot history will be temporarily shortened to 2 days. Upon completion of the controller migration, snapshot data history will build as usual.
This mandatory maintenance will be scheduled to occur between November 2019 and March 2020, during an off-hours window to minimize impact. Customers will receive the following maintenance notifications:
Controller Migration Scheduled Notifications [beginning at least 4 weeks in advance, though some will receive more advance notice]
4) Do you have details on how this impacts customers with proxy configs on their agents?
Since the controller fully qualified domain name (FQDN) will remain the same — agents will still talk to customer.saas.appdynamics.com (where customer is the customer’s specific account name) because we will redirect the DNS to the new controller host(s).
5) Why is the access period of historical snapshots being temporarily reduced?
Given the large volume of data that snapshots represent and the time required to transfer that amount of data, we are unable to migrate all snapshots. We believe the best solution is to provide access to the most recent, most frequently used snapshots. Customers can manually archive older snapshots individually by following the documentation. Archived snapshots will be migrated during the controller migration.
6) Is there any other data that will not be moved?
