[ISS Support Case] Downgrading - Uninstall Reinstall Guidance

Last updated: March 7th, 2025

Description

Some time ago you provided us with a tech note regarding downgrading the CDP 2023 R2 back to CDP 2023 when installed on a common single host with System Platform 2023 R2 installed. REF CASE 88042 Since then, we are considering our options with a potential upgrade to System Platform 2023 R2 SP1. Ideally, we would prefer to do this with the supplied CDP 2023 R2 SP1 version, as this supports the latest .NET 8.0 from a security perspective. However, due to legacy PLC firmware in the field, we wish to know if the downgrade method we used previously is still possible with R2 SP1.
