Recently I finally bit the bullet and decided to bring the vCenter portion of a vSphere environment up to version 6.5. Since the migration from a Windows based vCenter to the VCSA is now a supported path I thought it would also be a good time to migrate to the appliance as well. So with that I ran through a few blogs I found in regards to the migration, checked out the vSphere Upgrade Guide and peeled through a number KB’s looking for gotchya’s. With my knowledge in hand I headed into the migration.
At this point I had already migrated my external windows based PSC to version 6.5 and got started on the migration of the windows-based vCenter Server. Following the wizard I was prompted for the typical SSO information along with where I would like to place the appliance. The problem though came when I was prompted to select a deployment size for my new VCSA. My only options available were Large and X-Large. Might not be a big deal if in fact this environment required this amount of resources – Looking at the table below those deployment sizes are scoped to fit at a 1000 host and above mark.
Did this environment have 1000+ hosts and 10000+ VMs? Absolute
