OTRS import: When importing queues with a parent queue to Zammad the migration then stops

[Mark Hero]

Used Zammad Version

6.2

Environment

• Installation method: any
• Operating system: any
• Database + version: any
• Plugin: Znuny4OTRS-ZammadMigrator-6.0.7.opm

Actual behaviour

If a queue with a parent queue is created in Znuny the name of the queue looks like "IT::Hardware" with two colons in it. Now the import to Zammad stops with the following error

Expected behaviour

The import does not crash and a group with a parent group is created in Zammad.

Steps to reproduce the behaviour

• Create a Queue like IT in Znuny
• Create a Queue with Subqueue IT in Znuny
• Import the data from Znuny to Zammad
