After upgrading to Spectrum 22.2.5 the following messages are seen in the VNM.OUT:
Jan 31 20:48:18 NCM_POLICY_DEBUG TRACE at IHHostConfig.cc(9814): IHHostConfig::convert_policies Policy mh = 0x20509cc is not migrated, using the old policy definition
Release : 22.2.5+
The NCM Policy Definition table was updated in the SSdb.
This message is benign and logged because the Policy Definition changed/updated in the SSdb. All the message is saying is that it didn't migrate using the old definition for that policy. Instead, it recreated it. Nothing to worry about.
The message is logged when ncm_debug is enabled. Check to see if debug is enabled and if so and not needed disable debug.
$SPECROOT/SS/.vnmrc
ncm_debug=true
change to:
ncm_debug=false
