We just got a new FlowCollector and we reconfigured a few exporters to send Netflow data to the new FlowCollector
is there a way to move the data collected to the new flow collector ? or delete all of them for that Flowcollector in batches instead of one by one
If you want to replace old FC to new FC and discard the old one, you need to reconfigure all Exporter's configuration one by one to send FlowData to the new FC "in each Exporter". After all exporter sending Flow to new FC, just discard old FC. All exporter side configuration is separately handled in each exporter, not FC side configuration. So if we delete exporter information in old FC, all exporter's configuration still working. In this way, old collected FC data is deleted and we can't see it after replacement.
If you want to replace FC with old data, you need to do complete migration with FC's configuration and data backup.restore. I recommend to open TAC in this case. They have a clear procedure for this migration. In this case, all exporter's configuration still working because old FC and new FC has the same IP.
OK about SMC in HA mode I find some guide of how to configure it, but FC in HA mode I didnt find anything, could you please send me any link of how configure FC in HA mode?
And how about flow exporter under device I can Set two Flow collector address?
Yes, flow device needs to send same Flow data to two FC address. Normal Flow device can only send Flow data to single collector address. So at this case you need Flow device to send Flow data to UDP Director and UDPD sends same data to two FC address.
At this environment two FC has same Flow data but HAed SMC can handle these duplicated data as single one.
