About updates
Hello,community!
I have a question about updates. More precisely about their differences. Tell me, what is the difference between, for example, KB5019758 and KB4489622 for Exhange 2013? Both in the description have CU23. And one more question. How do I determine that after an update, the Schema needs to be updated? Where is this indicated?
Thank's
- Hello!
The KB4489622 is the CU 23 for Exchange Server 2013.
The KB5019758 is a Security udpate. ( If Microsoft detects vulnerabilites in Exchange until the next CU is available, a security update for Exchange is launched for the installation ).
About the Schema, when you install your first Exchange server you already need to prepare the Schema for it. After that, if you don't miss any CU, you don't need to worry about that, as the CU takes care for you. Anyway, at any CU installation documentation you'll see which are the changes and te requisites.
If you plan the CU updates for your environment correctly, you should not face any problem. 🙂 ( Keeping an eye to the possible vulnerabilities detected and corresponding security updates ).
Hope this clarifies your doubts. Have a good day!

Thanks a lot for the detailed answer. Now I see that I need to study Exchange in more detail.
KB5019758 and KB4489622 are both updates for Microsoft Exchange Server 2013, but they are different updates. KB5019758 is a security update for Exchange Server 2013 CU23, released in June 2021, while KB4489622 is an update rollup for Exchange Server 2013 CU23, released in March 2019. While both updates include CU23, they may contain different fixes, features, and security patches.
To determine whether a schema update is required after installing an Exchange Server update, you can check the release notes or documentation provided by Microsoft. In general, a schema update is required when installing a new version of Exchange Server or when applying certain updates that modify the schema. Microsoft typically provides guidance and instructions for performing schema updates as part of the update documentation.
In the case of Exchange Server 2013, it's worth noting that schema updates are typically required when upgrading to a new cumulative update or service pack, but may not be required for smaller updates like security patches or update rollups. However, it's always a good idea to carefully review the documentation and release notes for any update or patch before installing it, to ensure that you are aware of any potential impact on your system or environment
