We have an RMA switch that has arrived with 6.1 and we need to downgrade to install in stack of VSP4850'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 ?

Hi Siobhan,

VSP4850 is not a stackable switch - so I presume you mean clustered with another switch.
The answer is yes you can downgrade it 100%, but as I recall you might have to downgrade to release 5.0 first because I think it will fail if you try directly (will not hurt the switch - so try - but go to 5.0 first if it does not take it).

I would note through that there have been many fixes since 4.2.3 - and also 4.2.3 is out of support, so you might be better thinking about upgrading the others instead....

Many Thanks,
Matt

What are the versions of ERS4850 - because the SW versions you mention above (4.2.3 and 6.1) are both VSP code releases - not ERS4850......
