Hi, We have 2 datacenters and one is primary and second one is for DR. We use snapmirror to replicate the data to the DR and both are running 8.3.2P9. We are planning to upgrade the DR cluster first to 9.2 and after 2-3 weeks upgrade the primary to 9.2.
Here is the question, during the 2-3 weeks where the DR is at higher level and the DR senerio happens, whether we will be able to reverse resync to primary which is a lower level ?
thanks.
