Hi Brenden.
The V12 site will be an upgrade of the existing V11 site, so V11 portal engine -> V12 portal engine.
The client then wants a sub-domain with new content. Normally this would be created as a second site within the admin portal and using a sub-domain license created from the main domain license, but this would also have to be portal engine.
My question was whether this 2nd site could be created using Xperience V13 and .NET Core, i.e. under a fresh Kentico installation, using a V13 sub-domain license key created from the main domain license?
