 ### Limitations
 
-- Upgrading a Basic tier cache results in brief unavailability and data loss.
+- When you upgrade a cache in the Basic tier, it is unavailable for several minutes and results in data loss.
 - Upgrading on geo-replicated cache isn't supported. You must manually unlink the cache instances before upgrading.
 - Upgrading a cache with a dependency on Cloud Services isn't supported. You should migrate your cache instance to virtual machine scale set before upgrading. For more information, see [Caches with a dependency on Cloud Services (classic)](./cache-faq.yml) for details on cloud services hosted caches.
