Cisco does not recommend to do replication between different versions of ACS.

I have also seen dissimilar versions to cause problems like database corruption, though it might work in some case.

To be on safer side keep both ACS on same version and only then replicate.

Following link can help you configure replication:

For configuring Backup ACS incase primary fails you need to configure backup server on the AAA client (router,switch) because only AAA client will forward the request to secondary server in case primary fails.
