I'm facing some issues with the old OPSEC LEA. We migrated to the latest version of Splunk Add-on for Check Point OPSEC LEA and trying to stop the logs receiving from the old add-on but some reason it is still receiving the logs. Do you have any thoughts? please share with me.
Upgrading OPSEC LEA from version 2.x to 4.00 and later is tantamount to installing a completely new add-on. In a strict sense, you do not UPGRADE your old version to 4.0 and beyond but merely disable or uninstall your old add-on and install a new one. Therefore, if you do not disable or uninstall your old version (2.x) OPSEC LEA TA and still leave it running, of course you will still get data ingested into Splunk from that old TA.
For information about OPSEC LEA upgrade, please refer to the Splunk documentation here:
Hope this helps. Thanks!
