Migrating from Old Pool to a Completly New Pool

This made possible transfer everything fast with ZFS replication (let’s call A your old pool, B the new one)

  • perform a backup (always a good choice)
  • shutdown down the server
  • add all the disks
  • create the new raidz1 pool B
  • added with edit stops all apps or VM
  • setup an insite push replication task, A as source, B as target. Recursive and full file system options must be selected
  • run the job just once, will be pretty fast
  • when finished, export your A pool WITHOUT nor erase configuration and wipe disks (so you still have your data in)
  • rename B pool with the previous A pools name
