• Unified CCE 12.5(1) is not named as a direct upgrade source for Unified CCE 15.0(1); the guide names only 12.5(2) and 12.6(x). in context
• The supported upgrade path to Unified CCE 15.0(1) is from Unified CCE 12.5(2) or 12.6(x). in context
• Unified CCE 15.0(1) upgrades land on either Windows Server 2019 with SQL Server 2019 or Windows Server 2022 with SQL Server 2022. in context
• Upgrading a Unified CCE deployment from Windows Server 2016 with SQL Server 2017 to Windows Server 2019 with SQL Server 2019 is not supported; such deployments must move to Windows Server 2022 with SQL Server 2022. in context
• Unified CCE 12.5(1) is not named as a direct in-place-upgrade source to 15.0(1): the guide's Supported Upgrade Paths table lists exactly one in-place-upgrade row, 'Unified CCE 12.5(2)/12.6(x) to Unified CCE 15.0(1)', naming no 12.5(1) row. But the same guide's Upgrade Prerequisites section documents a 12.5(1)-to-15.0(1) reporting migration: 'When you migrate the reporting from 12.5(1) or 12.5(2) to 15.0(1), you will encounter changes related to report filters.' The gap is therefore partial: a full platform in-place upgrade from 12.5(1) is undocumented, while a 12.5(1) reporting migration to 15.0(1) is documented. in context
