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

http://svnbook.red-bean.com/nightly/en/svn.reposadmin.planning.html#svn.reposadmin.basics.backends.tbl-1

It happens but should be removed, for an example see
http://svn.apache.org/r1573371

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.
