- DSMUPGRD QUERYDB (Display information about a V5 database)
Use the DSMUPGRD QUERYDB utility to display information about the database and recovery log for a V5 server. You can use the information to estimate the amount of storage that will be required for the database and recovery log when the server is upgraded to V7.1. - DSMUPGRD PREPAREDB (Prepare a V5 database for upgrade)
Use the DSMUPGRD PREPAREDB utility to prepare a server database for upgrade to V7.1. You must run this utility before using the DSMUPGRD EXTRACTDB utility. - DELETE VOLHISTORY (Delete sequential volume history information)
The DELETE VOLHISTORY command is used to delete volume history file records that are no longer needed (for example, records for obsolete database backup volumes). In a migration from z/OS® to AIX® or Linux on System z®, issue this command on the V5 server to specify the device class of volumes that must be deleted to prepare for the migration. - DSMUPGRD EXTRACTDB (Extract data from a V5 server database)
Use the DSMUPGRD EXTRACTDB utility to extract data from a server database. The data can be inserted into a version 7.1 server database either later or at the same time as the extraction process. - DSMUPGRD EXTEND DB (Extend the size of the database)
Use this utility on a V5 database to extend its size. Use this utility only when an error occurs during the upgrade process that indicates that you need additional database space to continue. - DSMUPGRD EXTEND LOG (Extend the size of the recovery log)
Use this utility on a V5 server to extend the size of the recovery log when the ANR9999D LOGSEG message was issued during the upgrade process, which indicates that you need additional log space to continue with the upgrade process. 
DSMUPGRD UPDATE (Create backup registry entries for a V5 server instance)
Use this utility to create registry entries for a V5 server instance if a problem in the upgrade process has removed the entries when they are still needed. For example, you can use this utility if you are upgrading a V5 server to V7.1 on the same system, and accidentally ran the DSMSERV LOADFORMAT utility before running the DSMUPGRD PREPAREDB utility.- Sample commands to run for validation of the database upgrade
Run commands before and after you upgrade a server to get a summary of information about the contents of the server database. Comparing the results of the commands before and after the upgrade can help confirm that all data transferred correctly. Samples provide a set of commands to start with.
