Updating on AWS

[pgb]

I'm running an EC2 instance on AWS that I created with the AMI for version 2.4.5-p1.

Yesterday I upgraded it to 21.02 through SSH (everything appears to be working normally), but after I did, I got an email from AWS Marketplace telling me there's an upgraded AMI in the marketplace:

We are writing to inform you that Netgate has added a new version to Netgate pfSense Firewall/VPN/Router on AWS Marketplace. As an existing customer, your subscription to the product, any running instances and access to previous versions are unaffected. However, Netgate does recommend you to update to the latest version, Netgate pfSense Firewall/VPN/Router/21.02 (update for v2.4.5-p1 and earlier) by visiting https://aws.amazon.com/marketplace/pp/B076TCMRWJ.

I figure my installation is just fine, since I've already updated it, but I've left wondering what's the proper procedure to update pfSense through an. updated AMI, with as little downtime as possible.
