 ### Data model changes from "dict-of-dicts" to "list-of-dicts"
 
-TODO: Removed type conversion
+In AVD 4.0.0 and across both `eos_designs` and `eos_cli_config_gen`, *all* "dict-of-dicts" data models with user-defined keys were changed to "list-of-dicts".
+In AVD 4.x inputs were auto-converted to the new data models.
+
+As of AVD 5.0.0 the automatic conversion from dict-of-dicts has been removed, so it is required to update the input data to the new data models.
+
+Errors will be raised for each data model not conforming to the list type when running AVD:
+
+```sh
+$ ansible-playbook playbook.yml
+<...>
+ERROR! [host1]: 'Validation Error: access_lists': {'ACL-01': {'sequence_numbers': {10: {'actio<...abbreviated...>4 any'}}}} is not of type 'list'
+```
+
+As an example, `ethernet_interfaces` was changed from:
+
+```yaml
+ethernet_intefaces:
+  Ethernet1:   # <-- User defined key
+    <...>
+```
+
+to:
+
+```yaml
+ethernet_interfaces:
+  - name: Ethernet1   # <-- "name" here is called the "primary_key" which must have a unique value across all list elements
+    <...>

+### No auto-conversion of old data model for `router_bgp.redistribute_routes` and `router_bgp.vrfs[].redistribute_routes`
+
+The change has been incorporated into `eos_designs`, so action is only required when defining new interfaces
+with `structured_config`, `custom_structured_configuration_`, or when using `eos_cli_config_gen` directly.
+
+The data models for `router_bgp.redistribute_routes` and `router_bgp.vrfs[].redistribute_routes` previously supported either a list of strings or a dict-of-dicts.
+In AVD 4.0.0 this was changed to a list-of-dicts with automatic conversion from any of the previous models into the new model.
+
+As of AVD 5.0.0 the automatic conversion from both of the previous models has been removed, so it is required to update the input data to the new data models.
