IIRC the DMS doesn't actually support 9.2, it requires 9.4 or newer I
believe. (You should double check that, my information might be old)

So you would have to start by upgrading your standalone cluster to 9.4 or
9.5 (PostgreSQL itself has no problem going directly to 9.5), and then use
DMS to move it to RDS.
