Preserving webform submissions on production site

I have the following situation.

We have a production site with a Webform page in use. Drupal content updates are first made on a staging site. After being reviewed and approved, the contents of the staging site would be pushed to update the production site. This could be done on a weekly basis, or as needed depending on the frequency of the content updates.

The staging site's files would be copied to the production site. The staging database would be exported and imported into the production database.

The plan is to overwrite the whole Drupal database of the production site, except preserving the Webform submission data already saved on the production site, so that they are not overwritten by the periodic content updates from the staging site.

Based on what I have read on Webform and by inspecting the database, it seems these two tables hold all the submissions data: "webform_submissions" and "webform_submitted_data".

I am wondering, in order not to overwrite the existing Webform submissions data on the production site, is it simply to exclude these two tables when making the database export from the staging database, so that these two tables would not be disturbed when importing the database?

Another idea is to use a module like Webform Import to first export the production site's Webform submissions data, then import the staging site's database (which has the whole Drupal database), finally re-import the submissions data from the production site.

However, it is simpler to just leave the two tables alone when importing the database export from the staging site.

Any advice and recommendation will be appreciated. Thank you.
