If you need to upgrade a EUM component (e.g., for a bug fix), you’ll first want to know how that upgrade would impact your entire environment and reporting.
The various AppDynamics components talk to each other by exposing APIs. They have a client/service relationship.
NOTE: See “How do I get started with upgrading my AppDynamics components?” for a complete collection of compatibility matrices
If you intend to upgrade your iOS Agent to the latest version:
Check to make sure you’re using at least the recommended minimum compatible Controller and EUM Server versions so all features for that agent version will function correctly and there will be no unexpected side effects.
If you update your Controller and EUM Server, you should plan to upgrade the Events Service to ensure that the Events Service version is higher than or equal to the EUM Server and Controller version.
Although we encourage you to keep your environment components within compatible versions (as listed in How do I get started with upgrading my AppDynamics components?), in some cases components can still be compatible if they vary within just the patch version.
To determine the minimum versions of the Controller and EUM Server required for supporting the latest features of the Mobile Agents, see the Mobile Agent Version and Deployment Support Matrix.
