Assuming you are really asking if you can use merge replication between your SQL Mobile application and the 64-Bit SQL Server, that depends on where your IIS insance is running (IIS is the gateway through which merge and RDA is brokered). The SQL Mobile server tools are not compatible with 64 bit architectures (yet) but that doesn't mean if you had SQL Server 2005 on a 64 bit server and the IIS/Server Tools on a separate 32 bit server that it wouldn't work.

Hi,
Same as the need of one of our client, SQL Server 2005 is running on a 64 bit server and IIS is running on a 32 bit server.
It works like a charm knowing we have between 120.000 and 160.000 records for each PDA using merge replication...
The only problem we encountered and solve quite easily was an "invalid parameter" on IIS side, the application pool was resetting connections after only 10 minutes when sometimes we need 15-20 minutes to do the first intialisation (the server is around 4 millions records and PDA are about 150 thousands...).
After this, normal replication are about 10 to 30 seconds, which is quite good.
It works great.
Fabien.
