Hello dear experts!
As Microsoft doesn't provide a VHD image of every Version of D365FO environment, I was trying to install a version 10.0.5 on my OneBox. Being guided by the following article https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/migration-upgrade/upgrade-latest-platform-update#apply-a-platform-update-to-environments-that-are-not-connected-to-lcs,
I reached the point, when a runbook needs to be generated. Although the only thing I've updated, was DefaultTopology.xml,

the system throws the following error on Runbook generation: "There is no service model selected for update"

Unfortunately a research in Internet hasn't brought me to any resolution.
Has anyone faced this issue before?
Thansk
