Hi Shrawan,

Mixed Environment Can Cause Failed to Load Tunnel Service Library 'daserver' Error (177458)
You might see the following error in the smps.log file when you upgrade the Policy Server to release 12.6.01 while CA Access Gateway is release 12.52 SP1 or a prior version:
Failed to load tunnel service library 'daserver'. System error: The specified module could not be found.
To suppress this error, do one of the following steps in the server.conf file that is located in the \secure-proxy\proxy-engine\conf folder:
- Delete AALoginService, Advanced Auth Application, and UI Application tags
- Mark the enable parameter to no in all the three tags as shown next

<Context name="Advanced Auth Application">

enable="no"
</Context>
<Context name="UI Application">
