We are Considering upgrading ED top 10.3
What Registry Versions are Compatible with new Enterprise Dashboard 10.3 version ?
You can connect the below Registries to a DevTest 10.3.0 Enterprise Dashboard:
You can connect an earlier version Registry to a later version Enterprise Dashboard, but not vice versa.
For example, a DevTest 10.3.0 Registry cannot connect to a DevTest 10.2.4 Enterprise Dashboard.
We are upgrading from 9.1, so is it possible to connect 9.1 Registry to 10.3, like with EnterpriseDashboardCICService ?
You would only need EnterpriseDashboardCIC running for Registries earlier than 9.1.0.
So I understand that in no way i can connect my 9.1 Registries to 10.3 ED ?
Yes, you should be able to connect your DevTest 9.1.0 Registry to a DevTest 10.3.0 Enterprise Dashboard.
