Can an ACS primary and backup/replica server be on different versions?

[jawill47ec]

Hello,

For (2) ACS' (for example:  an appliance 1120 running version 5.x and a quanta 1113 runnig version 4.x) can 1 primary be version 5.x with a replica at version 4.x?  If not, what are the requirements between setting up a primary and backup/replica for appliances?

thanks,

james

Hi,

No you cannot have replication done with the two device which you mentioned,

The only requirement is that the devices should  be on exactly same version, build and patach level  in order for replication to  work.
