Failover

In this blog we will do the actual failover.



Tip: Before you start it’s advisable to check what VM sizes ASR will provide for your target VMs, here the DS2V2 was resized to A5:

Test Failover

Running Test Failovers allow to do some pre checking without interrupting the production environment and gives you good indication on potential issues.

Test failovers consume resources, so you should clean up the test failover environments if you don’t want large Azure bills at the end of the month 

and confirm you want to delete

Unplanned failover

Now instead of selecting test failover plan, we choose unplanned failover were the old environment should be brought down and start the ARM VMs.

















Now hold on to your seat, cross your fingers and follow the progress in the portal:

If you configured everything well, you should see that everything is now running in the ARM model:



(don’t mind the shutdown problem, this behaviour is actually the result of the failed VM extentions test on ASM)

Checking the new resource group shows that all components are in place







 There are still a few things we need to do here, and that will be discussed in the next and last part of this blog series.
