Can you downgrade a ERS4850 on version 6.1 to 4.2.3 ?
We have an RMA switch that has arrived with 6.1 and we need to downgrade to install in stack of VSP4850 ERS4850's with 4.2.3 software. Can you downgrade this switch ? Or do we need to downgrade - will the V6.1 switch integrate in the 4.2.3 stack ? ...
