We have an Access 2000 split db on W2K Pro OS. We are moving to WINXP with Office 2003. Can the database be used simultaneously by both Access 2000 and Access 2003 users? Is there a conversion from the 2000 to 2003? If so, can users be prevented from accidentally converting the db until we are ready? We plan to update all users at roughly the same time, but plans like that rarely happen without hitches. Thanks!
