In Data migrator, Introduce mode to list and retry the migration of skipped entities

[yanavasileva]

User Story (Required on creation)

• As a process engineer, I want to keep track of skipped entities so that I can rerun the migration against them.

Functional Requirements (Required before implementation)

The Migrator has a dedicated mode to list and retry the migration of skipped entities. This allows fixing them on the C7 side.

Technical Requirements (Required before implementation)

• Implement an option to query for skipped instances.
• Querying should be paginated so as not to run into out-of-memory exceptions.
• Should we limit the output to the console if the result is too huge?
  • Is this a common practice for shell scripts? If the output is too huge you could also do ./start.sh --list-skipped > skipped-instances.txt.
  • We could just accept this for now and wait for user feedback.
• The Migrator has a dedicated mode to list skipped entities.
  • E.g., a flag on the ./start.sh script called --list-skipped
• The Migrator has a dedicated mode to retry skipped entities.
  • E.g., a flag on the ./start.sh script called --retry-skipped
• It should be possible to combine the flags like this:
  --runtime --list-skipped
--history --retry-skipped
