Citect SCADA 2018 V8.1 - O/S compatibility

i have 2 only Citect SCADA 2018 V8.1 servers running on WIN 7, all my workstations are running same on WIN10 without issue for around 3 years now.

next year the servers will be upgraded, i know Citect SCADA 2018 V8.1 is listed as compatible for WIN10 only but when i buy new servers its likely they will be WIN 11 O/S.

this means i will have a hardware and software upgrade to do. as i have redundant servers is there a white paper or procedure to do an online upgrade i can follow for this?

also (although not recommended) has anyone used Citect SCADA 2018 V8.1 on WIN 11 temporarily while upgrading?

Hi Thijs-Jan , What Bradley stated above is true. We recently tested Citect SCADA 2018 R2 RTM and Plant SCADA 2020 R2 RTM on Windows 11 and Server 2022. The Tech Matrix has now been marked as compatible…

Hi Alan,

Unfortunately we haven't conducted compatibility testing with Citect SCADA 2018 and Windows 11/Windows Server 2019/2022 and there is no plan to do so.

2018 R2 and later have been tested with Windows 11, 2019 and 2022.

The installation guide contains the procedure for doing online upgrades.

Hi Bradley,
The Technology Matrix (On https://softwaresupportsp.aveva.com/#/) of Citect 2018 R2 and Plant SCADA 2020 do not list Windows 11 or server 2022 in the OS Environment Compatibility matrix. Will the new windows versions be added?

Hi Thijs-Jan ,

The Tech Matrix has now been marked as compatible for these new OS. Will will make sure that GCS is made aware of this change, so that it is officially supported.

In general, there is not anything stopping customers running older Citect version on newer OS. It will likely work without any issue (usually highly dependent on .NET and other Microsoft tools). But it is good to get confirmation from R&D / Support that specific combinations are fully supported.
