 ### Supported tiers and SKUs
 
 Index tuning is supported on all [currently available tiers](concepts-compute.md): Burstable, General Purpose, and Memory Optimized, and on any [currently supported compute SKU](concepts-compute.md) with at least 4 vCores.
 
 > [!IMPORTANT]  
-> If a server has index tuning enabled and is scaled down to a compute with less than the minimum number of required vCores, the feature will remain enabled. Because the feature is not supported on servers with less than 4 vCores, ifyou plan to enable it in a server which is less than 4 vCores, or you plan to scale down your instance to less than 4 vCores, make sure you disable index tuning first, setting `index_tuning.mode`to `OFF`.
