Upgrade Scenarios

There are three ways to perform the upgrade to Matrix Server 3.4.0 and

the corresponding version of the PolyServe Solution Packs:

• Perform a rolling upgrade. In this procedure, servers are removed

from the matrix, upgraded, and returned to the matrix one-at-a-time.

No downtime is required. See Chapter 2, “Rolling Upgrades” on page

• Upgrade all servers at once. This procedure requires that the matrix be

completely shut down during the upgrade. See Chapter 3, “Non-

Rolling Upgrades” on page 14.

• Upgrade the servers in two groups. This method minimizes overall

downtime. See Chapter 3, “Non-Rolling Upgrades” on page 14.
