Plan for Exchange updates
- [Instructor] When updating the Exchange Server 2019, there are two main types of updates. Service packs and cumulative updates. There are also security updates that are occasionally added individually, but these tend to be rolled into one of these two at some point. Service packs are full of security updates and feature updates. While the cumulative updates are entirely new installations of Exchange, they will install over your existing one without issue. Updates also have to do with the server role itself. Not all updates apply to both the mailbox and edge transport rules, which are our two Exchange 2019 roles. Besides manually running the updates on each Exchange Server, we can also push them out using group policy or system center configuration manager. There's also Windows updates that need to happen to the operating system itself to make sure it's secure and up to date. Sometimes these updates require a reboot and change management. For Exchange downtime we need to plan for downtime after hours. We need to have a database availability group for high availability, and we should also look at a change management meeting. Database availability groups allow to have a synchronized copy of your mailbox database in another location on another server. This can allow you to update one server while keeping services to the clients still running. Change management meetings are also important for planning for downtime. We need to get with our management team, and talk about the impact any downtime would cause. This means meeting with the department heads and finding the best time for everyone to have these interruptions. By planning for and executing Exchange updates, you'll be able to avoid critical downtime to your organization, and keep your Exchange Server up to date.
