Before Starting

Migrating the Controller often results from the need to move the Controller to new hardware due to increased load. Before starting, make sure that the new hardware meets the Splunk AppDynamics requirements as described in Controller System Requirements. Specifically, you should review the Controller hardware performance profiles and the hardware requirements per profile information to verify that the target Controller hardware meets the RAM size and Disk I/O requirements.

Warning: You will need to update the MAC address associated with your license since licenses are tied to the machine MAC addresses. You can also acquire new license files for the new Controller hardware by sending an email to salesops@appdynamics.com and request a new license file or two new licenses, if upgrading to an HA pair. See Apply or Update a License File for more information.

If you are performing a migration and upgrade for a 4.3 version Controller, you should first migrate the Controller. Then, you can upgrade the Controller to 4.5 or higher by installing the Enterprise Console and using the Discover & Upgrade feature. This also applies to migrations involving different OS environments.

Warning: VMotioning, or migrating a VMware guest with a running Controller inside it from one host to another, is not supported. Doing so will lead to dropped metrics and UI performance problems.
