Can you please help with these queries.
if we can install both on same machine, I can go with docker version of 17.03.0-ce right ?
In installation guide of Analytics mentioned that
"Install the appropriate version of Docker for your operating system before installing the ThingWorx Analytics Server. On the Install Docker Engine site, find the installation instructions for your host operating system and follow them to install Docker version 17.03.0-ce or later."
As I mentioned in my query my OS is windows server 2012 R2.
The documentation can always be find in the Reference Document page: https://support.ptc.com/appserver/cs/doc/refdoc.jsp?p=browse_results&Product=ThingWorx+Analytics&Release=8.1&DocType=

Regarding the support of Windows 2012, there is unfortunately no official support at this time .
It is expected to work but it had not be possible to QA this OS, so it is not officially supported.
You can see the supported OS in the ThingWorx Analytics Server docker installation guide: https://support.ptc.com/WCMS/files/173637/en/ThingWorx-Analytics-Docker-Installation-Guide-8-1.pdf
