Has anyone got any tips for sizing a move from VM running sql instances from our current IaaS to Azure managed instance? Primary areas that we are concerned about are disk performance on the Azure side. Guess the primary question we have is do we need to go with Business Critical or General Purpose?
We've run a sizing tool, however it seemed more geared towards giving details when migrating to a single sql database using DTU as the sizing guide rather than a managed instance sizing guide.
Would be grateful if anyone has any good pointers/urls or maybe a sizing tool that we haven't come across just yet.
