Hi,
Thanks for your reply.
Firstly, the previous existing records will not be deleted since the aging and scavenging is not enabled. Even though we enable this feature in the future, the static records we manually created also will not be deleted. Aging and scavenging only delete dynamic aged records beyond No-refresh interval + Refresh interval.
>>The zone may have previously got updated from appliances that are not working part of domain- and we do not want to get them deleted now.
May I know how did above appliances records updated? Were they static records or dynamic records? If they were not part of domain and dynamic records, they cannot update after you change the setting to only secure update. However, if you don’t enable aging and scavenging for this zone, these existing records will not be deleted.
Best Regards,
Sunny
