Description:
This issue was because during AMSG 3.1.3 release, there was no release from BWSE side which bundles platform 3.1.3.
BWSE 5.9.2 has lower platform version i.e. 3.1.2

In this case, while installing BWSE 5.9.2 on top of AMSG 3.1.3 following two features get downgraded.
Administrator Server
TIBCO Host

Workaround for this issue is to disable above 2 features during installation.

In GUI, this can be done just by un-checking the checkboxes. But, for silent mode installation “Product Feature Settings” are not available in silent file.
That’s why one cannot install BWSE 5.9.2 on top of AMSG 3.1.3 in silent mode.

Later we worked around this issue by manually adding following product features settings in BWSE silent file for installing BWSE 5.9.2 GA on top of AMSG 3.1.3GA and it worked :
//
<!--Profiles Selection-->
<!-- The 'selectedProfiles' value is a comma separated list of profiles to install. If a profile is listed which does not exist, then it is ignored. At least one profile must be listed if useInstallProfile is set to true -->
&ltentry key="useInstallProfile"&gtfalse</entry>
&ltentry key="selectedProfiles"&gtAdministration,Runtime Host,SOA Development</entry>

<!--Product Feature Settings-->
&ltentry key="feature_BWSE Runtime_bwse"&gttrue</entry>
&ltentry key="feature_BWSE Development Tools_bwse"&gtfalse</entry>
&ltentry key="feature_BWSE Documentation_bwse"&gttrue</entry>
&ltentry key="feature_Administrator Server_amx-plat-installer"&gtfalse</entry>
&ltentry key="feature_TIBCO Host_amx-plat-installer"&gtfalse</entry>

This issue does not exist with BWSE 5.9.3/AMX 3.1.5.
