replication of databases with different backends???

["lux-integ" <lux-integ@btconnect.com>]

Greetings,

I have two computers with these:-

host 1:
--cpu amd64 3 cores
--os blfs linux-3.10.24, openldap-2.4.33 with bdb backend


host 2:
--cpu amd64 3 cores
--os blfs linux-3.10.24, openldap-2.4.33 with sql backend

QUESTION:
can I replicate these databases over each host  (in other words
 can I for example    do N-ray multimaster syncrepl  (  
http://www.openldap.org/doc/admin24/replication.html )
or another type of replication in view of the different backends ?


thanks in advance
sincerely
