We have a 16 node SQL Server 2016 failover cluster with around 20 SQL Server instances and total number of databases around 600.
Since we are upgrading our hardware to Hyper-Converged infrastructure which has limitations with failover clusters with shared disks then we have to migrate our cluster to availability groups.
My question is: what should we consider if we are going to migrate to SQL Server availability groups? can we have the same number of instances and multiple availability groups on the same servers as we have in the current failover cluster?
Appreciate if someone guide us with some technet articles which talks about similar cases.
