Checking API and Database Connectivity

To work properly, the migration script must have access to the system APIs and the oss database (see Requirements for details). You can check that the APIs and database are accessible from the server where you run the migration script by using the api_connectivity_test.py script:

Go to the directory where the migration script is located.
Run the api_connectivity_test.py script:
```
python api_connectivity_test.py
```
In the script's output, check that all connectivity tests completed successfully:
```
...
billing xmpRpc - PASS
...
api_entry - PASS
...
open_api - PASS
...
aps_api - PASS
...
DB – PASS
...
```
If any of those connectivity test failed, you must fix that and run the api_connectivity_test.py script again.
