AppDynamics Datacenter Controller Migration
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:
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:
No. For operational reasons, it is not possible to reschedule this maintenance.
In line with standard maintenance practices, the maintenance window will be 60 minutes. The metrics loss and UI downtime is expected to be under 5 minutes.
After the controller migration, you can still use your own domain to send emails — see these instructions for how to get verified. If you use <account-name>.saas.appdynamics.com to send emails no action is needed.
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).
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.
All historical metrics, EUM, and analytics data will be available after the migration. Only APM events and snapshots history beyond 2 days, which are very large data sets, will not be moved. APM events and snapshots can be archived by following the APM events documentation and snapshots documentation.
Appdynamics has traffic redirection in place which will forward traffic during the DNS change.
Check status.appdynamics.com (or the maintenance notfication emails themselves) for the message sent the week of November 4 entitled "Appdynamics IP Address Change."
