Data base upgrade

Hi friends

I am upgrading application from Ax 4.0 to Ax 5.0

but here thing is my client is using Oracle DB for Ax 4.0,

he wants to change Sql Server for 5.0;

so client needed to migrate from Oracle Db to SQL DB

my thing is if i’ll install Empty SQL DB with AX 5.0, is it possible to Migration Data base from Oracle DB to SQL DB

is it possible to connect with Ax 5.0?

Is it possible to migrate the application before the data migration?

In future i’ll migrate data base but i need to show data exactly what exist on oracle DB

this definitely should help, but you probably found it since

Thanks for reply
