1 **Service affecting** final template to use the **R19** single lane release. This upgrade is service-affecting, as all instances have to be recreated.
2
3 **Process**
4 We upgrade in one step to use the new **R19** release of the cloud template. This step is service affecting.
5
6 **Overview**
7 * Remove need for recycling underlying instance when adding containers to machine
8
9 **Update Steps**
10 * Use the final **R19** template (service affecting) (duration: 15 minutes)
11 * User actions after applying the final template:
12 ** Check if all runtimes are reachable by Deploy Architecture.
13 ** Check if all flows have been installed according to the active release.
14 ** Check if messages pass through the model by verifying a critical message flow in external systems.

16 **Remarks**
17 Adding/moving/deleting containers from machines will now not replace the underlying instances. This was only the case for singlelanes. Doublelanes do not have this behaviour and are not affected.
