Hi @Sb5,
I believe your question goes beyond the Pulse as product itself and rather , I suggest to follow Amazon’s procedure, this has its variants by database, but according to Amazon’s documentation [1] and [2] is completely possible.
Now, once the database is on SQL Server RDS[1] the only thing to do from the Pulse side is to configure the SQL server connection in the Pulse.cfg.
[1] Import data into an Amazon RDS DB instance (browsed on Sept, 2019)
[2] Importing and exporting SQL Server databases using native backup and restore - Amazon Relational Database Service (browsed on Sept, 2019)
Best Regards,
Erik
