Hi,
Last week end we upgrade the platform from version 21 to 31 (Dev VM). While upgrade it failed and there are only two option in the screen 1. Resume and 2. Abort
We tried Resume couple of time and after that we aborted the operation. After this when we opened D365 in browser it always says Service unavailable.
Below is the runbook execution output.
The step 20 failed with the following error:
The step started
Error during AOS update: Exception calling "CreateRuntimeProvider" with "1" argument(s): "Serialization version mismatch detect, make sure the runtime dlls are in sync with the deployed metadata. Version of file '189'. Version of dll '187'." [Log: C:\DynamicsAX\RunbookExecution-ExecuteParallelRunbook-f6245db3-d14f-4f17-b6b3-28abcec860a4_I0_R0\output\Step20\AosService-Update_20191217163424.log]
The step failed

at Microsoft.Dynamics.AX.AXUpdateInstaller.Program.InstallUpdate(String[] args)
at Microsoft.Dynamics.AX.AXUpdateInstaller.Program.Main(String[] args)
How to solve this? In worst case how to roll back to working condition.
