I am researching upgrading to vSphere 5.5 and Esxi 5.5. Our present vSphere vCenter server environment has approx 100 guest os servers. It has been brought to my attention that the MS SQL Express is not recommende to use with over 50 guest vms. My question is should I install a new vCenter server with on a new guest os from the beginning with new W2K8 os or upgrade the existing vCenter server and upgrade the SQL Express and upgrade the vCenter server to 5.5. \
Thanks for any info or suggestions,
