Moving to a new VM was not the issue, my mistake was thinking the OS 
version was staying the same.

Then:

On old VM:

"take offline full backup (PG_DATA folder alone)  using OS command"

On new VM:
"Restore offline full backup (PG_DATA folder alone) using OS command"

Followed by installing new Postgres version could be dealt with using 
pg_upgrade. Once I was corrected on what was actually going on then 
doing a dump/restore or logical replication became better choices.
