Hi, @sns ,

I have changed the tag to office-online-server-general as the thread is more related to OOS.

Updates for OOS are generally released every month. This is the latest update:

Hi Seward & Jerry Xu,

Thank you, Please clarify my below 4 questions:

in Our Lab & Prod OOS servers are with below versions, so with this we can go head and install feb security patches in both lab and prod?

I have high level steps attached to update these latest security patches ( planning to use same procedure I used 6 months ago to update July patches ). Please correct. 71988-highlevel-steps-to-update-securit-patches-for-offi.txt

By installing these Feb updates in OOS , does it have any impact?

in last year June 2020 we noticed memory consumption is 80 percent on OOS server after installing July 2020 updates memory consumption came down. so now also we can expect to reduce this memory consumption post feb updates as we are seeing again 80 percent memory consumption now.

Microsoft documents the update strategy at Apply software updates to Office Online Server. I have written a script based on this which you can find at AWACPM.

As far as memory consumption, I haven't seen any issues myself.

And as far as applicability, if you haven't updated to Feb 2021, yes you should be able to apply it given the base was installed with the November 2018 ISO.
