An on-premises data gateway is software that you install in an on-premises network. The gateway facilitates access to data in that network.
If you have installed the gateway already and are looking forward to updating it to the current version released by Microsoft, then this section is for you. I am trying to highlight the steps that I have implemented in my organization which can help to provide the one-place reference for you to update your gateways.
I have used the November 2019 update from Microsoft while working on this blog, and Microsoft may change the steps in the future, but they can still be used as a reference, as per my understanding.
