> Can we try to do backup restoration with scylla manager from 5.4 to 6.0?  
> Before restoring can we create keyspace in tablets enabled and then do restoration from manager ?

> @avi one last confirmation needed,  
> Scylla 6.0 running comes only with elastic scaling which are done by tablets.  
> Scylla autoscaling comes with operator.  
> Scylla 6.0 running on VM doesn’t comes with autoscaling.  
> Am i correct ?
