| Reverting does **not** require undeploying [[nbs-7]]. If you want to remove RTR and keep NBS 7 running, | ||
| this page is the whole procedure. |

docs/undeploy-nbs7.md is titled "Undeploy NBS 7" so I think this should remain "undeploying"

| ### 2d. Disable CDC on NBS_SRTE | ||
|
|
||
| `NBS_SRTE` is reference data and RTR is its only known CDC consumer. Confirm that for your environment, | ||
| then disable the capture instances and the database-level flag: | ||
|
|
||
| ```sql | ||
| USE NBS_SRTE; | ||
|
|
||
| -- Generate the per-table statements | ||
| SELECT 'EXEC sys.sp_cdc_disable_table @source_schema = N''' + s.name + | ||
| ''', @source_name = N''' + t.name + | ||
| ''', @capture_instance = N''' + ct.capture_instance + ''';' AS statement_to_run | ||
| FROM cdc.change_tables ct | ||
| JOIN sys.tables t ON t.object_id = ct.source_object_id | ||
| JOIN sys.schemas s ON s.schema_id = t.schema_id | ||
| ORDER BY t.name; | ||
| ``` |

We could also provide a script that checks if CDC was enabled for any table other than what RTR requires. If so, that would indicate CDC was enabled for some other purpose on SRTE.

Added a script that looks for CDC-enabled tables that are outside of the scope of RTR
Although what if:
- Table already had CDC enabled
- Bootstrap script specifies to enable it
- We turn it off
That's bad. There's another method using timestamps, let me expand on this...
