Product and database interactions
You cannot have both the 32-bit and 64-bit version of OpenEdge for Windows installed on the same system. However, both versions can access the same OpenEdge database, so there is no need to convert or do a dump and load when migrating from Windows 32-bit to Windows 64-bit.
The 32-bit client (prowin32.exe) supplied with the Windows 64-bit product for Data Dictionary and Data Administration functions can access an offline database in single-user mode. If a 64-bit server is started against the database, the 32-bit client cannot connect using shared memory, and must connect to the 64-bit server using a client/server connection.
