Connection Servers in a Replicated Group,” on page 36.

downgrade that instance to an earlier version. After you upgrade all View Connection Server instances
in a replicated group, you cannot add another instance that runs an earlier version.

used as desktop sources, as full-clone desktops in a pool, and as individual desktops in a manual pool.
See “Upgrade View Agent,” on page 48.

you thoroughly understand the irreversible changes at each stage before you upgrade your production
environments.
