separating branch offices from head office into different SQL Servers

Hi,

Does Dynamics AX 2009 support multiple SQL Server?

we have branch offices in foreign countries and their access to AX is slow.

so I want to know if I can setup a local SQL Server database and a local AOS in the branch offices and replicate the data to the head office.

(But head office stuff has to be pushed back to the branch office)

I know that SQL Server support the replication, but is there something integrated in AX 2009 for this?

or does a 2 way replication setup in SQL Server is enough and supported?

I know that 2009 is old, but I do not have the choice here :-)
