I don't know if it is explictly documented anywhere.  The closest I can
get is:

It happens but should be removed, for an example see

The BDB data files are portable but the BDB environment files are
platform dependent.  Switching platforms for BDB generally requires a
BDB recover operation to replace the BDB environment files, and may
require a BDB upgrade operation if the BDB library version changes.

FSFS repositories need no special operations.
