To whom it may be useful.

I picked it up this script in the same forum and had modified it a little. It helped me move all my wal/db from HDD to SSD in my case and can be used to replace an older SSD with new SSD with wal/db.

Just pass all OSD names and have a good night sleep. The process is extremely slow but it works without any intervention and performance degradation.
