The good news for many of my customers wanting to deploy IBM Docs is that version 1.0.7 has just been released and not only does it now support Windows 2012 (no Windows 2012 R2 but v1.0.6 only supported Windows 2008 R2) but previously the key IBM Docs Application and IBM Docs Proxy required Linux as an operating system meaning we had to not only add at least one additional server but that server had to be Linux. This was especially frustrating since the Conversion Server required Windows and wasn’t itself supported on Linux so to fully deploy IBM Docs 1.0.6 you needed at least one Linux AND one Windows server
As of 1.0.7 Windows 2008 R2 and Windows 2012 support all IBM Docs components. Unfortunately the Linux operating system does still not support the Conversion Server but at least we have one OS to use if we want. Full specifications here
Well done IBM.
