How to Safely Disable Scheduler Roles Tasks During Platform Upgrade ?


I can't seem to find a satisfactory answer in the documentation, so I thought some experts here might have it. 

Which of the asynchronous background tasks of the Scheduler Role can be safely disabled during platform upgrade or migration? Email is probably safe, but what about the other two, process and timers

Does the platform utilise them during various stages of the upgrade process, such as recompiling ,preparation, and execution?

Kind regards,

Hello Robin,
They are not used during the upgrade process for the steps you mentioned, and you can disable them all.
My question is when and why are you disabling them?
