Troubleshooting the form-factor migration from v2018

Troubleshoot problems with migrating from v2018 to v10 on a different form factor.

Topics:

Script help

You can access help for all the migration scripts by using the --help argument:
python3 <script_file_name> --help

Restarting migration

On the target system, if the register_gateway_portals_in_target.py, update_to_new_portals.py, or update_to_new_gateways.py scripts fail, run the load script 3 again, with the -reset_gateway_portal flag as shown:
python3 load_v2018_data_to_v10.py ... -reset_gateway_portal
This resets the portals and deletes the gateway pods.
Note: If you deleted the data directory after you registered the Gateways or Portals, but want to use the same target API Connect system that you already installed, then extract the data again:

Factory reset of portal subsystem

The migration load script with -reset_gateway_portal does a factory reset of your portal subsystems. Portals can also be factory reset by following these steps:
  1. Log in to the portal www pod admin container: 
    kubectl exec -it <portal www pod> -c admin -n <apic namespace> -- bash
  2. Run the command: 
    curl -X DELETE -k --cert /etc/nginx/ssl/portal-director-client-both.pem  https://localhost:3009/v2/portal/factory-reset
  3. Use the list_sites command to check that all sites are deleted.
  4. Check health of the Portal subsystem.

Avoid error when a gateway is already registered to another API manager

Error messages
Error: An error occurred communicating with the gateways subsystem at 'some_url' (status: 400, response: '"Unable to perform initial registration for API Management.
Error: The API Connect Gateway Service is already registered to another API Manager instance"

To fix this first try restarting the gateways, or if you are using Gateway appliances, restart them. If the problem persists, reload the v2018 data with the load_v2018_data_to_v10.py script and repeat the remaining steps of the migration process, starting with Step 5 in Restoring the v2018 data to the v10 target deployment.
