F5 LTM Point Release Upgrade (12.1.2)

We are looking to upgrade the point release version of our F5 LTM due to vulnerability issue . Currently we are running on 12.1.2.1.0.271 HF1 and plan to move to 12.1.2.2.0.276-HF2 . I am having some confusion on how to start with it . I already downloaded the new image Hotfix-BIGIP-12.1.2.2.0.276-HF2 .

I understand that there's a lot of things we need to consider while doing this . By the way we are running Active-Standby pair of LTM.

Thanks In advance .

Here's the current settings we have . If I understand correctly, we can use HD1.2 or HD1.3 to install the new point release version ?
