Download and install the latest PUTTools package on all TPA nodes.
Run pre_migration_prep.pl on the source system. The script performs a variety of checks for potential problems that must be resolved prior to continuing the migration process.Each Teradata Database release has a unique subdirectory in the PUTTools directory for the pre-migration script applicable to that release. The folder is /opt/teradata/PUTTools/tdnn.xx.xx.xx, where nn is the major release number (15, 16, 17, and so forth), and xx.xx.xx is either the literal string xx.xx.xx (for initial releases, like 15.00, 16.00, 17.00, and so forth) or the minor release number (like 10, for 15.10 or 16.10) followed by xx.xx. Use the scripts in the preupgrade subdirectory.
- Create a temporary directory and change directory (cd) to that directory.
From a temporary directory, run the perl command to start the script:
perl /opt/teradata/PUTTools/tdnn.xx.xx.xx/preupgrade/pre_migration_prep.pl system_name/dbc,dbc_password
The script generates output report files to the temporary directory created in step 1.
