Recent-ish versions of Rivendell (starting with v2.1.0) will in fact refuse to 
run if they detect that the DB version is different from the one that it knows 
how to use.  This is to guard against the DB corruption that can otherwise 
ensue by operating with mis-matched versions.

To determine which versions are ‘compatible’ DB-wise, just look at the first 
two numbers of the Rivendell package version.  If they are the same, then they 
can be safely mixed.

Some examples:

2.10.3 <=> 2.10.0       Safe to use (2.10 == 2.10)
2.9.0 <=> 2.9.1 Safe to use (2.9 == 2.9)
2.10.3 <=> 2.9.0        UNSAFE! (2.10 != 2.9)

Cheers!
