After a migration to VCF 9.0, an administrator must import only logging data newer than 90 days from Aria Operations for Logs 8.x into VCF Operations…

The official method for migrating historical data from a standalone VMware Aria Operations for Logs instance to a new one (such as VCF Operations for Logs) is to use the built-in data migration utility. This process is initiated from the administrative user interface of the target (new) VCF Operations for Logs instance. The utility allows the administrator to connect to the source instance and specify a time range for the log data to be imported, fulfilling the requirement to import only data newer than 90 days.

A. Configure log forwarding in Aria Operations for Logs.

Log forwarding is designed to send new log events in real-time to another destination; it is not a tool for migrating existing historical log data.

B. Import logs from an NFS archive used for Aria Operations for Logs.

This is not the standard or recommended procedure. The correct method is a direct, instance-to-instance transfer using the dedicated migration tool, not a manual import from an archive.

D. Initiate the transfer from Aria Operations for Logs.

The data migration process is a "pull" operation. It must be initiated from the administrative interface of the target (new) VCF Operations for Logs instance, not pushed from the source (old) instance.
