We are in the process of migrating our Management Suit (Mgmt + log + event server) from R80.40 to R81.10, which all run on open hardware.
We are creating new VMs for all three to migrate and will be performing migrate_server export and import to move the databases.
Wanted clarification on few question if someone can assist
1. Do we need to run the migrate_server export on all three servers or on the management server only. If not on the other two then do we just create new log and event server and re-establish SIC with new Mgmt server.
2. For the new management server, if we have the same hostname and IP address, I believe we do not have to perform re-establish of SIC with gateways.
3. For the log server migration, what is the best way of transferring logs from old server to new server so its viewable after migration. Does it need to be re-indexed? Would appreciate if someone can provide reference sk or guides for this.
