1.3 Preliminary Tasks for Upgrade Installations

1.3.1 Prepare to Convert Databases

As of PMDF V6.5, the format of PMDF databases has changed from Berkeley DB (SleepyCat) to PBL. If you are upgrading from V6.4 or earlier, you must either convert or rebuild all of your databases. Before the upgrade, there are several steps you must take to prepare for the database format change.

If you do not have sources for databases that you wish to use pmdf crdb to rebuild after the upgrade, you must run pmdf dumpdb on those databases before the upgrade to generate the corresponding sources.

Databases created by pmdf db, such as personal alias databases, can best be handled by before the upgrade using the pmdf db write command to create a source file, and then after the upgrade using the pmdf db run command on that source file to create the database in the current format.

1.3.2 Save Tailor File

If you have made any changes to your PMDF tailor file (/etc/pmdf_tailor), you must save this file before you upgrade because it will be overwritten by the installation.

After upgrading, you should check the new pmdf_tailor file and merge in any changes that you made to your version of the file.
