How to correctly move the databases Arcsight ESM 6.0?
1. How to correctly move the databases Arcsight ESM 6.0 from the old server to the new one?
2. How to correctly move a database server Arcsight ESM 6.0 server Arcsight ESM 6.5?
What exactly do you mean by databases? The events, or the mysql database containing the ESM resources?
The ESM resources can be exported and imported using export_system_tables and import_system_tables (refer to admin guide for details).
For the events: I'm not sure whether it is possible to copy the online event store. If you have archiving enabled, you should be able to copy the archives (under /opt/arcsight/logger/data/archives/) to the new server and run the restorearchives command (refer to admin guide for details).
Alternatively, you could attempt stopping all arcsight services and simply copying the whole /opt/arcsight directory to the new server (after performing a fresh install on that new server, in order to register the services etc.). I'm not sure however whether that is really a supported approach. It resembles the suggested approach for rolling back an upgrade, but that is usually on the same server...
From 6.0 to 6.5, I'm not sure whether you can simply move databases. I guess moving it to 6.0 and then upgrading to 6.5 would make more sense. Especially for restoring event archives, this procedure changed from 6.0 to 6.5. The restorearchives command does not work for 6.5. And I don't think importing the system tables of 6.0 to a 6.5 install is possible.
