ArcSight Logger Appliance L7700 - Arcsight_data_XXX files delete

Hi Team,

Can you assist me in deleting Arcsight_data_XXXX Files from the folder /opt/data/logger/ since these files are consumed 100% all the available 26T disk space.

I got to know these files will recycled by Application however I need to perform Data Migration from L7600 to L7700, while running data migration utility, I am getting Delete Failed and Copy Failed due to insufficient space.

Thanks in Advance.
