Migrating to ArcSDE 64 bit on Windows when the existing DBMS is 64 bit

If you have an existing 32-bit ArcSDE installation, you cannot directly upgrade to a 64-bit installation.

If you are running ArcSDE as a 32-bit application connecting to an existing 32-bit database in a 64-bit database management system (DBMS) on a 64-bit server, follow the instructions in this topic.

Steps:

1. Create a backup of the database.
2. Stop the ArcSDE service, if one is running.

   sdemon -o shutdown -i <service> -s <server_name> -p <ArcSDE_administrator_password>

   For details on using the sdemon command, consult the ArcSDE Administration Command Reference provided with the ArcSDE component of ArcGIS Server Enterprise.

3. Make sure there are no users currently making a direct connection to the geodatabase.
4. Grant upgrade permissions to the ArcSDE administrative user.
5. Set up the 64-bit DBMS on a 64-bit server.
6. Re-create user accounts in the new database or on the new server, if using operating system accounts.
7. Install the 64-bit version of the ArcSDE component on a 64-bit server (either the one on which the DBMS resides or a remote one). Do not proceed with the Post Installation wizard.
8. Upgrade the geodatabase.
9. If your site uses an ArcSDE service to connect to the geodatabase, run a custom postinstallation setup using the Post Installation wizard on the 64-bit server.
