Omar,
Yes, you are correct in that:
- NFA Console - is only avaiable under Windows Server. There are NO plans on having it available under RHEL.
- NFA Harvester - is available for Windows and RHEL.
TBH, even though I am a big Linux fan (and run it just about everywhere and have done so for decades), I would be reluctant to specify a Linux Harverster. There are known issues around doing this sort of thing for the Harvester and so it is best avoided.
Concerning dates - there is a difference between EOS and EOL - in particular with Windows Server editions. The end of mainstream support for Win2k22 is on 13th Oct 2026. However, this is just mainstream support. There are several levels of support that Microsoft go into. Mainstream is only the first level. The actual EOL date for Win2k22 is not till 24th Oct 2031. Therefore, you have at least 5 years left for 2k22. As such, you should still expect to see service packs and that sort of thing released for 2k22 for awhile yet.
I should add that the above doesn't preclude me stating that it is good to support new Windows releases - I am absolutely for this.
Also, I think that there are .NET dependencies and the such like that means that you are stuck with these Windows versions.
The obvious path to think about is DX Flow. However, I understand that this is more of a revolution rather than evolution as far as upgrade paths are concerned.
Regards,
Ed
