Migrating to ArcSDE 64 bit on Linux or UNIX when the existing DBMS is 32 bit

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

The simplest way to move your data is to use the tools provided by your database management system (DBMS) to move the entire database from the 32-bit instance to a 64-bit instance.

Steps:

First, prepare the new server.
1. Set up a 64-bit version of the DBMS on a 64-bit server.
2. If the process you will use to move your data or database to the new server does not include the users, re-create user accounts in the new DBMS or on the new server if using operating system logins.
3. If you will be using an ArcSDE service for connections to the geodatabase, install the 64-bit ArcSDE application server on a 64-bit server (either the one on which the DBMS resides or a remote one).

   See the installation guide provided with the ArcSDE application server for instructions.

Next, prepare your existing geodatabase to be moved.
4. Stop the ArcSDE service, if one is running.

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

   ArcSDE command line tools and their documentation are installed with the ArcSDE application server.

5. Be sure there are no users currently connected to the geodatabase.

   You can check this from the Connections tab of the Geodatabase Administration dialog box in ArcGIS for Desktop.

6. Create a backup of the database.
Lastly, move your geodatabase to the new DBMS.
7. To move the database, consult your DBMS documentation and use the method you prefer, then do the following:
   1. If you are moving to a new version of ArcGIS at the same time that you migrated your geodatabase to 64 bit, upgrade your geodatabase.

      Follow the preparation and upgrade instructions that are specific to your DBMS and the geodatabase release to which you want to upgrade.

   2. If you will use an ArcSDE service for geodatabase connections, edit the ArcSDE and operating system service files to contain the service entry, then use the sdemon command to start the service.
   3. Reset your geodatabase connections in client applications to connect to the new server. This includes redirecting any geodatabase replications.
8. After testing to be sure everything is working properly in the new geodatabase, uninstall the ArcSDE application server from the 32-bit server.
