If you have a RAID group with a single HDD (Basic) RAID option then you should be able to add another drive and migrate to a RAID1 (with 2 drives). Once that is done you can replace the first drive with 16TB.https://www.synology.com/en-global/knowledgebase/DSM/help/DSM/StorageManager/storage_pool_change_raid_typehttps://www.synology.com/en-global/knowledgebase/DSM/help/DSM/StorageManager/storage_pool_expand_add_diskEven though size do not match, all data will be duplicated to a new drive.I hope this helps.
