From EXT4 to BTRFS on Synology RS1219+ The Long Slow WAY - 817

Migrating the old drives over from the old DS411j went without a glitch. But now I still have the old EXT4 file system. and I really want to changes to BTRFS, that has check and error correction.
I did not do this the easy way,, but it did turn out to be a way with zero downtime.
