If you are making major OS changes when you are upgrading the DSA packages, use a VM&F upgrade.
A VM&F upgrade automatically reboots the server. For all other upgrades, a reboot of the server is not required.

- Change NFSMASTERHOSTNAME to MASTERHOSTNAME.
If you are upgrading to DSA 16.20 or later, you must include the following new parameters:
- Install the new release of DSA software on the BAR servers as you did initially. However, in the Network Subnet Selection, select the Ethernet interface where all of the BAR servers are configured.
