+Every even-numbered minor version of {product-title} is an Extended Update Support (EUS) version. However, Kubernetes design mandates serial minor version updates, so you cannot directly update from one EUS version to the next. An EUS-to-EUS update starts with updating {VirtProductName} to the latest z-stream of the next odd-numbered minor version. Next, update {product-title} to the target EUS version. When the {product-title} update succeeds, the corresponding update for {VirtProductName} becomes available. You can now update {VirtProductName} to the target EUS version.
 
-After you update from the source EUS version to the next odd-numbered minor version, you must sequentially update {VirtProductName} to all z-stream releases of that minor version that are on your update path. When you have upgraded to the latest applicable z-stream version, you can then update {product-title} to the target EUS minor version.

+[NOTE]
+====
+You can directly update {VirtProductName} to the latest z-stream release of your current minor version without applying each intermediate z-stream update.
