Hi ,
The first step is to migrate the DSERIES server to win2016 using the same database, installed in the same SQL server, by executing the folliwing steps:
------------
1 - take note of DSERIES version/build (to verify what patches are applied) on 32 dSeries environment
2 - Install DSERIES 64-bit (pointing to a temporary new DB)
3 - Start 64bit dSeries server (i.e. after installing server, dSeriesServer need to be started at least ones)
4 - Stop 64bit dSeries server
5 - apply the 64-bit DSERIES patch on newly installed dSeries server (to make new DSERIES server to be in the same build number as old dseries server)
6 - Start 64bit dSeries server, ensure that the dSeries Sever is at the patched build level
7 - Stop 64bit dSeries server
8 - replace db.properties file with the file backed up in step 3.
9 - Update 64bit dSeriesServer "\<CA WA Directory>\conf\server.properties" file with "espresso.guid" value from their 32bit dSeriesServer installation
Note: If there are any "extra/additional properties/configurations" mentioned in 32bit "server.properties" file which are not present in 64bit dSeriesServer, do add them.
10 - run validatedbconnection.bat command to ensure the 64bit dSeriesServer can connect on the old/existing Oracle DB
11 - stop 32bit DSERIES server
12 - Take old/existing DB backup (this is to have a safe point in case if we need to revert/fall back)
13 - (this step is required only when 64bit dSeriesServer is installed on different workstation than their old/32bit dSeriesServer workstation)
Update database: To update "ESP_CONFIG_PROPERTY" table to use "64bit dSeriesServer workstation name"
14- start 64bit DSERIES server.
15 - verify agents, workload-processing etc on 64bit dSeriesServer to ensure it is processing workload similar to 32bit dSeriesServer.
16 - If the transition is satisfactory you can plan to shutdown/uninstall DSERIES 32-bit

Once the above is completed, the second step is to migrate the DB to the new SQL server 2014. To accomplish this, you can follow the procedures described in the following article:
https://comm.support.ca.com/kb/how-to-configure-dseries-if-necessary-to-move-the-database-to-another-machine/kb000038650
Of course, I would suggest you to execute the above instructions in a test environment first.
And the most important, if you have any doubts, we highly recommend you to open a support ticket. This is a very critical operation.
