Manual upgrade
Use the manual upgrade instead of the Fixlet upgrade when you upgrade a DSA multiple server environment.
Note: Before starting the upgrade in a DSA environment, ensure that all DSA Servers have already
received the new masthead from the primary BigFix Server.
Note: During the upgrade of a DSA server, ensure that no services
are running on all the other DSA servers to prevent the upgrading
system from becoming unstable when a replication process starts against
it.
