Back up the matrix configuration
The Matrix Server service should not be running when you perform the backup. The
default location for the matrix configuration files is %Program Files%\PolyServe\
MatrixServer\conf on the drive where you installed Matrix Server. Back up the
following from the conf directory:
The files directly under \conf
The \conf\debug subdirectory
Do not back up the mounts and licenses subdirectories.
Back up PSFS filesystems
You should have recent backups of all PSFS filesystems for disaster recovery purposes.
Upgrade scenarios
There are three ways to perform the upgrade to Matrix Server 4.1.0 and the
corresponding versions of the HP PolyServe Software:
Perform a rolling upgrade. In this procedure, servers are removed from the matrix,
upgraded, and returned to the matrix one-at-a-time. This method does not require
matrix downtime, but clients may experience brief outages during failovers. See
Chapter 2 on page 7.
Upgrade all servers at once. This procedure requires that the matrix be completely
shut down during the upgrade. See Chapter 3 on page 13.
Upgrade the servers in two groups. This method minimizes overall downtime. See
Chapter 3 on page 13.
