3.6.0 Matrix Server Upgrade Guide (5697-7085, February 2008)

Chapter 2: Overview 6

“The MxDB for SQL Server Upgrade Tool” on page 7 for more

information.

• The MxDB for SQL Server Instance Aliasing tool has been

incorporated into MxDB for SQL Server. If you are using Instance

Aliasing, note the following:

– Before performing the upgrade, make a copy of the sns.conf file.

Name the new file ia.conf and place it on a PSFS filesystem.

– Do not make any changes to the pre-3.6 Instance Aliasing

configuration file, sns.conf, during the upgrade.

– Chapter 5 describes changes needed for Instance Aliasing after the

upgrade to 3.6 is complete.

Back Up the Existing Matrix

Before starting the upgrade, we strongly recommend that you back up

the following:

• The membership partitions. During the upgrade, the new mxds

datastore will be installed on the membership partitions. Although

unlikely, I/O errors during this step could potentially damage a

membership partition, necessitating restoring the original

membership partitions.

• Your existing matrix configuration on each server. It is important to

preserve the original matrix configuration in case you need to back

out of the upgrade.

• PSFS filesystems. You should have recent backups of all PSFS

filesystems for disaster recovery purposes.

Back Up the Membership Partitions

Use the mpdump command to back up the membership partitions. The

following command backs up the partitions to the default backup

location, %Program Files%\Polyserve\matrixserver\conf\MP.backup.prev on

the drive where you installed Matrix Server. The file will then be included

when you back up the matrix configuration.

mpdump -F
