Question #: 104

You need to migrate a UFS file system named /production_ufs to a ZFS file system named /production_ufs. The /production_ufs file system cannot be taken down or be out of production during the migration, and the current /production_ufs file system must remain active until the /ptoduction_zfs file system is copied and ready.

Which method allows you to meet both requirements?

Option A seems like the way to go. Creating a snapshot of the UFS file system and then copying the data to the new ZFS file system allows me to keep the production system running while migrating the data. It's a clean and efficient approach.
