If you have a previous version of Messaging Server (32–bit) installed and configured on your system and you want to migrate your data to the 64–bit version, you can do so by following these steps for a side-by-side upgrade:
Using the Messaging Server 6.3 64–bit edition installer, install the 64–bit version of Messaging Server on the same system as your previous version of Messaging Server, but in a different directory (for example, in this procedure, /opt/sun/comms/messaging64/). See To Begin Installation.
To migrate the configuration and Message Store data from the previous version of Messaging Server, run the migrate-config (migration configuration) utility:
To back out the migration, run /opt/sun/comms/messaging64/sbin/migrate-config -u /opt/SUNWmsgsr, where -u is the undo flag.
Once you complete the migration, stop using the old server-root directory:
Update their PATH, any scripts referencing the old server-root location.
If you are using Legato Networker, be sure to update the server-root location in the configuration.
Replace the server-root location with the server-root binary location.
Start the new server with the following command:
If you need to back out the migration, use the —u (undo) flag:
/opt/sun/comms/messaging64/sbin/migrate-config —u old-base-dir
where old-base-dir is the old server-root directory.
To restart the old Messaging Server, use: old-base-dir/sbin/start-msg
