Questions regarding SWAP (new hardware)

Hi guys,

I have a few questions regarding a SWAP from a T4 HA cluster to a 3000 HA cluster.

1. Is there a recent document / migration guide from T-series to the new hardware (3000/3500)

- is there anything to consider (e.g. running a script) or it is only backup from the old one and restore on the new one?

 

2. It is a problem that I build the HA cluster (2 appliances active-passive) and update it in my office, then shut them down (the whole cluster) and boot the cluster at the customers?

3. Would it be better during the restore to shutdown the slave node and leave it off until the restore is finished (like at ssb migration) or not?

Thank you in advance

André
