You will have problems, and as we do not support this please do not post for others as will have a support nightmare dealing with issues from people trying to move to mySQL from Access.
Instead you should upsize your database from Access to SQL Server as both are Microsoft Relation Database Systems (RDMS). This is supported.
mySQL works best with PHP and we do see allot of issues caused by the rather buggy myODBC drivers that are required for ASP to talk to mySQL databases. The mySQL version is now only included for legacy reasons when SQL Server use to cost allot of money.
