2.2.10 Migrating Performance Expert Server from Version 2.1 to Version 2.2 on AIX To migrate Performance Expert Server from V2.1 to V2.2, do the following steps: Back up databases. You should back up all databases created by Performance Expert Server V2.1 in order to be able to rollback if the migration fails for any reason. The applicable databases are the master database DB2PM, and one performance database for every instance that has been monitored in the past. The list of the applicable databases can be determined by the Performance Expert Server configuration tool. Display the configuration data for every instance that shows the performance database used for the instance. Install Performance Expert Server V2.2 in a directory separate from Performance Expert Server V2.1. See 2.2.2, "Installing Performance Expert Server on AIX" on page 23 for how to install. Run the script pecentralize from the /<pe install path>/bin directory for each DB2 instance on which Performance Expert Server V2.1 ran before. Start the Performance Expert Server. Enter the command ./pestart from the /<pe install path>/bin directory.
