1. We have 4 series physical appliance. can we upgrade 18.104.22.168 version on 4 series appliance?
2. We have physical appliances for SA, broker,esa, archiver but log collector it is virtual so can we take backup on same Linux CentOS external device or need to take another CentOS for VLC.
3. we have DC and DR RSA, we should upgrade in one week interval or we need to upgrade same time.
4. Any new ports require to open for upgradation?
5. How many times take each component to complete upgrade, if I uses IDRAC.
