The Informant application both iOS and Android do not have the capability to sync data in from "source A" and sync that same data out using "source B".

Individual items such as single events or single tasks can be edited and have their sync assignment changed but there is not way to do this to entire sets of data or large numbers of tasks or events.

Example-

Informant is syncing to Google Calendars and to Infomrant Sync.  The Informant application cannot sync the events in from Google then sync those same events out to Informant Sync.  

Tasks and events will remain assigned to the sync service they arrived on inside of the Informant application.
