If I look at the instructions for the January updates:

I can see that it says you have to run "Install-csdatabase". But as far as I can see you dont need to that because the database are already at the correct level.

My question is if the last part about mobility and running bootstrapper is also redundant since I already have mobility enabled?
I guess the information is there since it is a cumulativeupdate so if you have not installed any of the previous updates you have to run both the database update and enable the mobility service?
