Thank you for your answer, but is it possible to know possible 'cooperations' here. Which Vmware software can have same DB instance and which not (and why if it possible, or VMware document).
We have already View, vCenter with Update manager, Director, Chargeback, Veeam and antivirus database. All these software now use it's own SQL express, but we think about full MS SQL version (because we'll increase amount of ESXi, VMs our environment will become bigger than now)
