We have in a central site two ACS 1113 version 4.2 working fine. We are going to install a brand new ACS 1121 version 5.2 in a alternate site. We checked the hardware profile for both ACS (1113 and 1121) in Cisco documentation and the ACS 1113 doesn't support version 5.2 and ACS 1121 doesn't support version 4.2.
For us is mandatory to have the database synchronization (replication). Is possible to do the replication between both ACS 1113 version 4.2 and ACS 1121 version 5.2? what need to do in order to provide replication? any configuration? any additional device?
