Post vRA upgrade to 7.3 of the primary vRA appliance node, reboot (as well as reboot of replica nodes), and successful startup of all IaaS services, the IaaS component upgrade is supposed to start automatically, assuming it hasn't been disabled by touching a file on the vRA console prior to that.
Assuming we've let the automated upgrade commence, what exactly occurs to the IaaS database (in our case MS-SQL)?
Are there any changes made to the IaaS database? Does the schema get updated, or something else?
Does this have to be done manually or is it in fact covered by the automated process?
