6 Logs and Error Handling

Detailed execution logs are available under $toolHome/logs. The main log for this script is migration_script.log. Log is always appended to, so all previous execution attempts will remain in the log. To get the log for only the most recent script execution, either move the existing log to another location or delete it before re-running the script.

If any step fails:

1. Check the error details in migration_script.log
2. Fix the issue (for example, missing permissions, incorrect environment variables, or insufficient disk space)
3. Rerun the script:

$ bash migration_script.sh

Since the script is idempotent, previously completed steps will be skipped, and execution will resume from the failed step onward.

Example Run:

bash migration_script.sh
