Changing passwords for primary and replicate ASE.

My replication system consists of following items: Sybase ASE as a primary, Sybase ASE as a replicate and Sybase RS between them, replicating data from primary to replicate ASE. I would like to change sa passwords for both of Sybase ASE. What are necessary steps to be done in order to follow that change on RS - if any? I am asking this because during RS setup I had to provide sa user name and password for both of ASE servers in .rs files, used by rs_init.

Best regards,

Vojislav
